AUR packaging of Raygui and libminiaudiohelpers

[Scyllinice]

Hello,

I did some AUR packages for Arch Linux users

https://aur.archlinux.org/packages/raygui
https://aur.archlinux.org/packages/libminiaudiohelpers

raylib is already packaged in Arch.

I was able to run the example app in this repository along with GUI and audio playing to make sure everything worked.

Hopefully this makes using your library easier for Arch users.

Heyo, you may not want to package libminiaudiohelpers, that thing literally exists just to check the sizes of some of the miniaudio structs expressly for raylib's raudio package. It's a whole thing, but it's entirely useless to anyone else except for Crystal people developing with raylib.

Yes, I noted in the description of that package that it's explicitly for this library.

It's just so that it's installable and removable via pacman and not something that someone needs to manually remove from their file system later.

If you feel strongly about it not being packaged, I can take it down. It didn't take long to do.
