Implement support for "Follow Me" feature

[mill1000]

Adds support for the "follow me" feature which allows the AC unit to receive temperature readings from the remote control.

From Midea's technology page

For this function to work

1. The remote control must be in range, and in line of sight of the AC unit
2. The remote control must manually be put in "follow me" mode so it sends temperature readings. It may be possible to leave this remote continuously in this mode, although battery life will likely decrease.

Close #89

Other references may refer to this function as "feel own", "personal feeling", "body sense" or "remote sense".

2 users have tested this function with mixed results. One was able to control this function on their device (#89 (comment)), the other was only able to turn the function off (#89 (comment)).

This might be a feature that is very device dependent.

Another approach for this feature.

The ESPHome midea component supports "follow me" via IR and can transmit any temperature sensor to the device.

In the example linked below, ESPHome can get any temperatures sensor from HA and transmit it to the AC unit.
