Windows 32 and 64 bit

[Dirk Hohndel]

So we have working 32bit builds up until today's master and I am thinking of ways to continue to have 32 bit builds, just potentially without the ability to download from the Garmin Descent Mk2 - unless I can fix that part.

Likely we'll just have two binaries, just like we have for macOS.
