Added support for Xiaomi Smart Space Heater 1S (zhimi.heater.mc2a)

[paranerd]

This PR adds support for Xiaomi Smart Space Heater 1S (zhimi.heater.mc2a).
Changes are minimal as the mc2a is basically identical to the mc2.

I own the device myself and can confirm that everything reads and performs as expected.

I would appreciate a quick merge as this is only the first step on my journey to natively integrate both devices into the main "Xiaomi" integration for Home Assistant.

Thanks a lot for the amazing foundation!

LGTM, thanks! 👍

In the future it will be easier to control these devices using the genericmiot integration, but that will require much more rewiring (that I've been slowly doing on my own..) so this will be a good stop-gap solution until that.

Ohh, please split the PR into two, one per each device.

I removed the p39 code and merged the recent changes into my branch but for some reason now macos-latest and windows-latest CI checks seem to be randomly failing - any ideas?

[rytilahti]

Those are known to be flaky, no worries on that :-)
