The Semtech SX1261, SX1262, and LLCC68, as the bytes they take and the answers they give.
Every command goes out in one SPI transaction framed by NSS, sent once the chip's BUSY
line is low, and a query's answer is read in the same transaction after its bytes. These
functions build the bytes and decode the answers from the SX1261/2 datasheet (Rev 2.2),
so a program with its own SPI access can drive the chip with nothing else.
