String manipulation filters for text sensors (#2393)
* initial text sensor filter POC

* fixed verbose logging

* add append, prepend, substitute filters

* add to lower, get to upper working without dummy

* clang lint

* more linting...

* std::move append and prepend filters

* fix verbose filter::input logging

* value.c_str() in input print

* lambda filter verbose log fix

* correct log tag, neaten to upper and to lower

* add on_raw_value automation/trigger
