Firstly, this abstract away behavior in the mod download models that can
also be applied to other types of resources into a superclass, allowing
other resource types to be implemented without so much code duplication.
For that, this also generalizes the APIs used (currently, ModrinthAPI
and FlameAPI) to be able to make requests to other types of resources.
It also does a general cleanup of both of those. In particular, this
makes use of std::optional instead of invalid values for errors and,
well, optional values :p
This is a squash of some commits that were becoming too interlaced
together to be cleanly separated.

This makes the metadata generation code a lot messier and harder to use,
but there's not really much else that can be done about it while
preserving all it's capabilities :(
At least we now have speed

This task is responsible for checking if the mod has metadata for a
specific provider, and create it if it doesn't.
In the context of the mod updater, this is not the best architecture,
since we do a single task for each mod. However, this way of structuring
it allows us to use it later on in more diverse scenarios.
This way we decouple this task from the mod updater, trading off some performance
(though that will be mitigated when we have a way of running arbitrary tasks
concurrently).
