TODO: Improvements

[Convery]

PackageFS should use miniz directly and operate on a memory-mapped archive rather than opening the file on disk for every operation.
va should try to parse the input at compiletime to reduce vars, i.e. va("%s %u\n", __FUNCTION__, rand()) -> va("funcname %u\n", rand())

[Convery]

PackageFS improvement added: b6ee931
va now has a specialization for loops: cceaeae

Still no compiletime evaluation of the formatting.
