[bug#42335] [PATCH guix-past] Add old versions of RGBDS

["Jakub Kądziołka" <kuba@kadziolka.net>]

* modules/past/packages/assembly.scm: New file.
---

This patch adds quite a few old versions of RGBDS. The project has quite
a history of small, possibly accidental breaking changes. As a
measurement of the necessity of this many different versions, I looked
into the git history of the Game Boy homebrew project that inspired this
addition.

The repository (which is unfortunately private) goes back to the days
of 0.2.5, and for almost all versions in that time range, there exists
a git commit that requires it.

I am on the fence on including versions 0.3.4 and 0.3.6. Their changelog
on GitHub was updated to warn of silent bugs with miscompilation
potential, and are what the 'almost' above accounts for ;)
I decided to omit them in the patch, hoping that this will prevent a
lost soul or two from tripping over those dangerous (in terms of
potential time loss) bugs.

I did not include versions 0.1.0 and 0.1.1, as they fail to compile and
I have no idea why.

This is my first patch for guix-past, so any review remarks specific to
pastraising are very much appreciated :)

Regards,
Jakub Kądziołka
