Module config 

The settings an SX126x is configured with, and the values its registers take.

Every value here comes from the SX1261/2 datasheet (Rev 2.2): the frequency word of section 13.4.1, the timeout steps of 13.1.4, the image calibration codes of 9.2.1, the LoRa modulation and packet parameters of 13.4.5 and 13.4.6, the power amplifier settings of 13.1.14 and 13.4.4, the sync words of Table 12-1, and the register values the chapter 15 workarounds write. The LoRa settings are built from a [LinkSettings], so a radio sends exactly the frames pamoja-lora computes the airtime of.
