Toshiba AC Remote Control B Support

Describe the bug

I have two indoor units installed close together and configured to use "Remote Control A" in the first unit and "Remote Control B" in the other unit to avoid interference, as described in the user manual below.

The current codebase has hardcoded the first five bytes 0xF20D03FC01 that only allows to emulate "Remote Control A". After capturing the IR signals of "Remote Control B", it is found that the only variance is on the leading 4 bits of the 3rd byte in the 72-bits command.

	Complete Command	3rd byte	4th byte
Remote Control A	0xF20D03FC0180010080	0x03	0xFC
Remote Control B	0xF20D13EC0180010080	0x13	0xEC

While the 4th byte's value is already derived by the checksum function automatically. Please help to enhance the support by enabling to specify remote type in the constructor and expose the field with getter, setter functions. Thank you.

In addition to the Remote Control B findings. Fan speed implementation was found to be different in remote control model WH-TA03NE/WH-TA04NE as below.

Fan Speed - First 4 bits of the 7th byte (byte[6]).
