* fix: FastLED SPI_DATA_RATE being truncated to 8 bits
FastLED expects SPI_DATA_RATE as an uint32_t, but we had it as uint8_t.
Fix that to avoid the data rate being truncated.
* fastled: allow specifying data rate
Previously, we've just taken the default data rate from FastLED.
However, that does not always work properly. In my case, I had a
slow level shifter that couldn't keep up with the 1 MHz data
rate default for WS2801. Long cabling might also be a reason why
one might want to reduce the data rate.
This will add a new optional "data_rate" config option where one
may specify the desired data rate as a frequency:
light:
- platform: fastled_spi
chipset: WS2801
data_pin: GPIO23
clock_pin: GPIO22
data_rate: 500kHz
num_leds: 178

A component to support [WLED](https://github.com/Aircoookie/WLED/wiki/UDP-Realtime-Control).
This allows to control addressable LEDs over WiFi/UDP, by pushing data right into LEDs.
The most useful to use [Prismatik](https://github.com/psieg/Lightpack) to create
an immersive effect on PC.
It supports all WLED protocols:
- WARLS
- DRGB
- DRGBW
- DNRGB
- WLED Notifier

to register `e131` addressable light effect.
This uses an internal implementation that

* uart: support begin and end methods.
A component may need to reset uart buffer/status by using begin() and
end() methods. This is useful for example when a component needs to be
sure it is not reading garbage from previously received data over uart.
For end() methods with software serial, disabling interrupt is
currently impossible because of a bug in esp8266 Core:

# MAX31865
Added support for the MAX31865 RTD-to-Digital Converter to measure PT100 and
similar RTDs. Verified with an Adafruit unit (product ID: 3328) and a PT100
probe.
# MAX31855
This was setup for incorrect SPI clock polarity and phase, and would return bad
data due to a race condition measuring on the wrong edge (verified with Saleae
Logic scope). Selecting the correct configuration fixes that problem.
Re-wrote the decode off the datasheet to handle error states better (sends NaN
as an update on failure to read temperature, which shows the value as Unknown
in Home Assistant).
Added the *optional* ability to monitor the internal high-precision temperature
sensor, which can be nice in some applications.
* Tests for MAX31855/MAX38165.
* Update style to match project rules.
Also fix CONF_REFERENCE_RESISTANCE and CONF_REFERENCE_TEMPERATURE being defined
multiple places. Missed this when I added them to const.py.
* Update style to match project rules.
Pylint line limit 101/100 ("missed it by that much").
Also apparently I can't read and patched the wrong line in max31855.cpp.
* Minor string/style cleanup.
There was a copy-paste leftover in max31855.cpp and max31865/sensor.py had
unnecessary whitespace.
* Improve MAX31865 fault detection and logging.
Log levels are more in-line with the documented descriptions.
Fault detection code is improved. A transient fault between reads is still
reported, but now only faults *during* a read cause the sensor to fail and
return NAN ("unknown" in Home Assistant).
* Update style to match project rules.
I just now realized the .clang-format and pylintrc files are included. D'oh!
* MAX31855 & MAX31865 code style alignment.
@OttoWinter caught some style mismatches, updated to match project better.
* Fix a lost '\' in max31865/sensor.py.

## Description:
Move esphome-core codebase into esphome (and a bunch of other refactors). See https://github.com/esphome/feature-requests/issues/97
Yes this is a shit ton of work and no there's no way to automate it :( But it will be worth it 👍
Progress:
- Core support (file copy etc): 80%
- Base Abstractions (light, switch): ~50%
- Integrations: ~10%
- Working? Yes, (but only with ported components).
Other refactors:
- Moves all codegen related stuff into a single class: `esphome.codegen` (imported as `cg`)
- Rework coroutine syntax
- Move from `component/platform.py` to `domain/component.py` structure as with HA
- Move all defaults out of C++ and into config validation.
- Remove `make_...` helpers from Application class. Reason: Merge conflicts with every single new integration.
- Pointer Variables are stored globally instead of locally in setup(). Reason: stack size limit.
Future work:
- Rework const.py - Move all `CONF_...` into a conf class (usage `conf.UPDATE_INTERVAL` vs `CONF_UPDATE_INTERVAL`). Reason: Less convoluted import block
- Enable loading from `custom_components` folder.
**Related issue (if applicable):** https://github.com/esphome/feature-requests/issues/97
**Pull request in [esphome-docs](https://github.com/esphome/esphome-docs) with documentation (if applicable):** esphome/esphome-docs#<esphome-docs PR number goes here>
## Checklist:
- [ ] The code change is tested and works locally.
- [ ] Tests have been added to verify that the new code works (under `tests/` folder).
If user exposed functionality or configuration variables are added/changed:
- [ ] Documentation added/updated in [esphomedocs](https://github.com/OttoWinter/esphomedocs).
