I ran the `bin/console spdx --fix` with different strategies for
different files. For most of the core classes, since they've been
drastically rebuilt, I've run it with the `git-blame` strategy, for for
the `src/Validators`, in which the API changed completely but the logic
remains the same, I use the `git-log` strategy.
The main focus of this change is to make those optional dependencies
more testable.
Unfortunately, some phpstan-ignores had to be included, since ::set
is not a PsrContainer method. We're only using it on tests though,
so it's fine. It targets our php-di container for testing purposes
only. The real implementation only relies on ::get.
This change also has the side effect of improving the performance
of those validators by not instantiating their databases each time
a iso validator is built, achieving massive improvements in those
scenarios. A small benchmark with no assertions was added to track
that improvement.
