Add option to download game files by patch or build number

[qin-tain]

What problem is this feature trying to solve?

The default behavior is to download the current version (solely with the -app option), and it would be great to download all game files pertaining to a specific gameplay patch.

How would you like it to be solved?

It would be great if we could directly download all game files using the patch or build number with options like -app <id> [-patch | -build] <id>.

Have you considered any alternative solutions

No

This would be hard to implement since there is only steamdb to get any manifestids from the buildid since steam appinfo only gives latest buildid and latest buildids/manifestids for all other branches in the appinfo
And steamdb does not allow access by bots or anything nor getting any info for this purpose sadly
