OOK and FSK should be both supported without the need of recompilation

[serialrf433]

Current Situation

Currently you are forced to choose if OOK or FSK is enabled. This is not what most users coming from rtl_433 expect. I was surprised why my reception (FSK transmitter) was not working. I had to spend much time to understand that for some unknown reason there is a switch between OOK and FSK rtl_433_esp . In platformio.ini there is: '-DOOK_MODULATION=true' ; False is FSK, True is OOK

Proposed Change

Please remove the need of
'-DOOK_MODULATION=true' ; False is FSK, True is OOK

OOK and FSK should be both just working at same time like known from the rtl_433 project users.
