Describe the bug

This is a feature request, not a bug report.

I have a BRC4C105 remote. It is detected as DAIKIN176, but the following items are different from the actual ones.

1. The set temperature of the air conditioner is 3°C lower in the library. (Cooling range 20-35)
2. The set temperature of the heating is 2℃ higher in the library. (Heating range 15-30)
3. There are "weak, strong, and rapid" settings for air volume, and it is detected as weak (Min), strong (Max), and rapid (Max).
4. Remote control mode can choose from his 1 to 6.

I changed the remote control mode from 1 to 6 with "cooling ON, 25 degrees, wind volume strong, wind direction swing".

Except for the checksum, there seems to be a change in the 3rd and 10th bytes.

Next, the fan speed was changed in three stages.

It seems that the lower byte of the 18th byte changes to 1,3,5.

Any chance to add support for this BRC4C105 remote?
