Scan length for AddressableScanEffect (#608)

Browse source 
* Added scan_length to AddressableScanEffect (allow more than one LED)

* Added check for scan length being longer than addressable light

* Added config option 'scan_length' to AddressableScanEffect (default: 1)

* Renamed scan_length to scan_width, removed erroneous length check

* Fixed indentation issue in addressable_light_effect.h
