=UltimateCodeWarrior 0de2b4fc5f Move Supreme OLED address to variant config 
Keep SH1106Display generic by relying on DISPLAY_ADDRESS while the T-Beam Supreme variant declares its 0x3D OLED address.

UltimateCodeWarriorand=UltimateCodeWarrior b8b6598dd3 Fix blank OLED on T-Beam Supreme V3 (I2C bus + 0x3D address) 
The SH1106 OLED on the LilyGo T-Beam Supreme V3 never lights up because:

1. The primary I2C bus (Wire) that the OLED, BME280 and magnetometer share
   is never initialized. The PMU/RTC use Wire1 (via XPowersLib); nothing
   brings up Wire on PIN_BOARD_SDA/PIN_BOARD_SCL, so the display driver
   talks on the wrong default pins.
2. The OLED is at I2C address 0x3D on this board (0x3C is taken by the
   QMC6310 magnetometer), but SH1106Display::begin() only tried 0x3C.

Initialize Wire for TBEAM_SUPREME_SX1262, and have SH1106Display::begin()
prefer 0x3D (only ever used by the OLED) before falling back to 0x3C.
Backwards-compatible for boards with the OLED at 0x3C.

Closes #2609
