Support SPI-only operation for sx127x, without software reset #37
Description
It would be nice to be able to use this library with an sx1276 or similar connected only to the SPI bus, without software-controlled access to RESET.
Some years ago I got this setup working in another project (RNode) by just writing all the state values in the device's memory to set them to the values they should have after a reset. That implementation is at https://github.com/markqvist/RNode_Firmware/pull/16/changes#diff-af2906d12afaaadb7d96df56a201452a24f987af5afcab94b2ab6ebf6577e2d3R729-R733
