Add support for Hitachi RAR-3U1 -remote for split unit AC

**Describe the problem you have/What new integration you would like**

I set up IR Remote Climate for hitachi_ac424 with ESP32dev and it works perfectly. I wanted to set up a receiver for the Hitachi RAR-3U1 remote. I used the example code and checked that the IR received receives the codes with dump: all and dump: raw.

The problem is that the received codes do nothing with ESPHome or Home assistant. I can control the AC split unit with home assistant and the receiver can read the IR signal but nothing happens. I think that this is because the remote is slightly different from either of the

**Please describe your use case for this integration and alternatives you've tried:**

I would like to have a receiver for the remote so the status would sync on home assistant

Start by reading the existing hitachi_ac424 and hitachi_ac344 climate integrations and comparing them with the supplied RAR-3U1 receiver and transmitter dumps. Done means the RAR-3U1 remote is supported and its received commands synchronize the split-unit status in Home Assistant.
