This alters the SX126x interface to raise the Overcurrent Protection limit to 140mA (the max allowed by RadioLib); These chipsets can draw a significant amount of power at their peak output, 122mA for the SX1262 and up to 134mA for the HPDTek 16 used on the Tbeam boards. This should stop any instance of tx power being clamped at the expense of a bit more power draw on long airtime.
I've noted the default 100mA limiter for RF95/SX127x. While I can't find a datasheet for the HPDTek 13/14 used on the SX127x Tbeam, it appears to be a direct copy of the HopeRF RFM9x, in which case the typical draw at 17dBm is 87mA. The PA_Boost mode on these chipset (+20dBm) isn't really useful due to low duty cycle.
