[bug#44978] Package v 0.1.30 in preparation for 0.2

[Ryan Prior]

Hi there! Bumping this again since vlang recently released 0.2, a major release has has a number of goodies I've asked for to help improve the quality of our package. I'm beginning the work to update our package to 0.2, and hopefully will also succeed at moving a few more of the vendored sources out into dedicated packages.

If I can get any feedback on this patch series it would be very appreciated!
