1.2.38 alpha device code is ready for alpha testers

This is the first alpha in about three weeks. With misc fixes that have been queued during that time…

  • @Michelepagot added windows versions of the install scripts
  • Based on user reports, increase the margin for Heltec battery detection and better heltec battery support in general (possibly still not ideal)
  • When running device code on linux, dynamically probe for the Pine64 LORA USB SX1262 radio
  • Fix wifi to work with no password networks
  • Fix #807 TCP API access was broken on ESP32s thanks @jfirwin and @pwilen for the good debugging
