Build both 32-bit and 64-bit installers

[Athanasius]

As we have develop working for both 32-bit and 64-bit now it's time to enable building 64-bit on GitHub. However, until 64-bit builds have been more widely tested we will still want to release 32-bit versions as well.

1. Tweak the current setup to add an explicit x86 to the installer file name.
2. Tweak the build script to take an 'arch' or similar CL arg to choose which bit-ness to build.
   1. This will entail changes to the WiX file(s) as a 64-bit version should be installed to Program Files, not Program Files (x86). Most likely we'll end up with two skeleton/template files, one for each, or splitting further ?
3. Tweak the GH build workflow to build both. Pay attention to WinSparkle.dll ! This means we'll have a single build, two .msi artifacts, and both should be added to the draft release. The hashes.sum should of course cover both.

So my other plugins seem to be working ok but PIL has broken on EDMC Screenshot again.

It seems it will need to be aware of whether it is 64 bit or 32?

Yes, if you want to have a single release that supports both then you'll probably have to just double up the PIL, i.e. PIL311 and PIL311_64 and import from the correct one with something like:

import platform

# No, Ath doesn't have the 'match' syntax in his head yet
if platform.architecture()[0] == '64bit':
	from Libs.PIL311_64 import Image
	...
elif platform.architecture()[0] == '32bit':
	from Libs.PIL311 import Image
	...
else:
	print("Panic!")
	...
