Update for T-Beam v1.2 + QOL

After some tests, I could only find an incorrect ampere meter. I didn't find any function in the new PMU - so yeah, it's a just "nice to know" for me so I removed it. Maybe someone can program it somehow, but I've tried a lot... And a little QOL Update - i dont need the display to be always on... Push the middle Button (IO38) and the OLED Display will be deactivated or activated. (It was desired with the Issues)

+# Ive updated Peterus's LoRa Software to the new T-Beam v1.2
+
+The new MPU hasnt the same functions as the old one - so the Ampere Meter isnt working anymore. Its a "nice to have" for me - so ive removed it...
+Nothing more to say ^^
+
+And a little QOL Update - i dont need the display to be always on... Push the middle Button (IO38) and the OLED Display will be deactivated or activated. (It was desired with the Issues)

 # LoRa APRS Tracker

 The LoRa APRS Tracker will work with very cheep hardware which you can buy from amazon, ebay or aliexpress.
