Version 5 based on Kuba's dirty fork.

NOTE: Component with CC1101 support is here: version 4 version 3 version 2

TODO:

• Add backward support for CC1101
• Add support for SX1262 (with limited frame length)
• ...
• Prepare packages for ready made boards (like UltimateReader) with displays, leds etc.
• Aggresive cleanup of wmbusmeters classes/structs
• Refactor traces/logs

DONE:

• Reuse CRCs and frame parsers from wmbusmeters
• Refactor 3out6 decoder
• Migrate to esp-idf and drop Arduino!
• Add support for SX1276
• Run receiver in separate task
• Drop all non wmbus related components from rf code part
• Allow to specify ASCII decription key
• Divide codebase to separate components (radio for radio communication, meter for meters (on which sensor may subscribe) and common for wmbusmeters code)
• Add triggers:
  • Radio->on packet (allow to blink on frame/telegram)
  • Meter->on telegram (allow e.g. to send whole telegram to MQTT)
• Re-pull of wmbusmeters code from upstream
• Reimplement TCP and UCP senders. Should be classes with common interface to use as action under Radio->on packet trigger
• Reimplement HEX and RTLWMBUS formatter to use as parameter of TCP/UDP action

For SX1276 radio you need to configure SPI instance as usual in ESPHome and additionally specify reset pin and IRQ pin (as DIO1). Interrupts are triggered on non empty FIFO.
