Because the _allFieldsCache attribute gets inherited, when it gets set for a class, all subclasses will also see that list rather than their own, potentially different list. To fix this, use a global dict indexing on the metadata class instead.

'Index' was a misnomer from the start since it contains critical information for the operation that can't be reconstructed (e.g. existing refs).

Also fix a small discrepancy between the commit list and bundle due to --reflog vs --all

Using the preferred file naming scheme of {moduleName}_{someInputURLDerivative}_{date}*, this allows mapping files to modules without ambiguity.

This requires at least Python 3.9.

E.g. `git+https://example.org/`

No need to quote the class name since the methods are not inside the class (anymore)

A significant part of this code (e.g. the module loading, HTTP retrieval, CLI) was mostly or entirely copied from snscrape.
