Custom component for ESPHome to expose a UART stream over WiFi or Ethernet. Can be used as a serial-to-wifi bridge as
known from ESPLink or ser2net by using ESPHome.
This component creates a TCP server listening on port 6638 (by default), and relays all data between the connected
clients and the serial port. It doesn't support any control sequences, telnet options or RFC 2217, just raw data.
