Si4735/Si4732: Volos Radio User Interface ported to ESP32 OLED_ALL_IN_ONE PU2CLR example sketch.

This user interface is based on Volos Projects sketch and the backend is based on ESP32 OLED_ALL_IN_ONE example from SI4735 library written by PU2CLR/Ricardo Caratti. I am using a Lilygo T-Display S3, which is an ESP32S3 board with a 1.9 inch display with a 8-Bit Parallel Interface, but I believe it will also run on Lilygo T-Embed with some fews adaptations in PIN numbers. This radio can tune FM, LW/MW/SW in AM or SSB mode and supports RDS on FM mode. All settings are continuously saved, so when resetting, all settings will return to the last state.
