support special IR code for ESP8266

### The problem

I want implement IR Remote use ESP8266 NodeMCU to control my exhaust-fan. as I know, LG or NEC format is :
Start (9us High & 4.5us Low) => 4 byte command => end
--
but my desired IR command is 5 byte command:
Start (9us High & 4.5us Low) => 5 byte command => end
--
I have read below link, except transmit_raw , no "Action" is suit for my request
[https://esphome.io/components/remote_transmitter.html](https://esphome.io/components/remote_transmitter.html?fbclid=IwAR1sWGfkJd7OX658dslMKNNgXkrHHEmO1q9bVny5L4m11Jt6vCO7sYriAKw)

Hope ESPHome support programmable IRTX which similar as transmit_rc_switch_raw Action in RF
Or hope ESPHome can support to add carrier frequency with 38KHz for transmit_rc_switch_raw action

Start with the remote_transmitter documentation and the transmit_rc_switch_raw action referenced in the issue. Clarify the required five-byte protocol, whether 38 kHz carrier support is needed, and the intended ESP8266 configuration; done means the supported behavior, configuration shape, and verification expectations are defined.
