Feature/nine additional alexa devices for presets (#2787)
* add 9 further alexa devices for calling presets 1-9

* use preset names from WLED for Alexa preset device names instead of hardcoded names

* update readme and version

* call alexaInit() at end of savePreset() to keep Alexa in sync with the preset IDs and names

* This reverts commit f8db06c7c5.

* change order to configured Alexa WLED name first, preset names afterwards

* fix status of devices when shown within Alexa, i.e. switching one preset on switches others off (except for alexaInvocationName)

* re-add getPresetName() after merge with master

* restore original readme for pull request

* restore original platformio.ini for pull request

* Logic simplification

* Pass string by reference

* Added number of presets check

* fix alexaInit() in case of alexaNumPresets==0
