Add 'Include'/'Exclude' options to limit packages used from a repository

'Include' allows limiting a repository to a allowlist of packages,
'Exclude' allows removing packages from a repository.

Implementation wise this is not the nicest as it goes via the
IndexTarget options, so we first parse our option value into a
vector, then we turn the vector into a string, and then vectorize
it again. That said, we support both "," and " " as separators due
to the construction (we split by "," then we join using " ").
