ESPHome-Konfigs für CC1101-Funksender/-empfänger inkl. Flash-Anleitung

Browse Source 
- Sender (ESP32-C3 Super Mini) und Empfänger (ESP32-S3), beide mit CC1101 433 MHz
- README dokumentiert USB-TTL-Anschluss, da der interne USB-Serial/JTAG
  nach Zadig unter Windows 11 nicht mehr nutzbar ist
- Verdrahtungsschema CC1101 als SVG
