Add optional RTS pin

[JosephAbbey]

Added an optional RTS pin to use if hardware automatic control flow is not available.

hcpbridge:
  is_connected:
    name: "HCP Connected"
  tx_pin: GPIO17
  rx_pin: GPIO18
  rts_pin: GPIO16

cover:
  - platform: hcpbridge
    name: Door

switch:
  - platform: hcpbridge
    name: Light


external_components:
    source: github://JosephAbbey/esphome-hcpbridge
    refresh: 0s # Ensure you always get the latest version

Tested and working on an ESP32 S3 DevKit-C 1.

After adding rst_pin I get an error in the code:

INFO ESPHome 2024.7.1
INFO Reading configuration /config/esphome/hormann.yaml...
INFO Updating https://github.com/mapero/esphome-hcpbridge.git@None
Failed config

hcpbridge: [source /config/esphome/hormann.yaml:57]
is_connected:
name: HCPBridge Connected
rx_pin: GPIO16
tx_pin: GPIO17

[rts_pin] is an invalid option for [hcpbridge]. Did you mean [tx_pin], [rx_pin]?
rts_pin: GPIO18

The pull request ist not merged yet so if you want to use the functionality of the rts pin you need to link jesephabbey's reppo in your yaml.

Yes, until it gets merged, you need to include:

    source: github://JosephAbbey/esphome-hcpbridge
    refresh: 0s # Ensure you always get the latest version

Sorry. I didn't read it, now it works properly.
