Broadlink RM4C (0x6539) mini support

[koenverhoeven]

The problem

The Broadlink integration doesn't support all RM4C mini devices. Every time after an update I have to add the following line to /./usr/local/lib/python3.8/site-packages/broadlink/init.py :
0x6539: (rm4, "RM4C mini", "Broadlink"),

This is the same issue in #45178. The broadlink python library has been updated to support the new devices but for some reason it is not getting included in the recent core updates. Very frustrating
