Run mypy in CI?

[DimitriPapadopoulos]

Add to .pre-commit-config.yaml to enforce that:

-   repo: https://github.com/pre-commit/mirrors-mypy
    rev: v1.13.0
    hooks:
     -  id: mypy
        files: "src"

That would be worth a try.

I would need help to fix all issues:

$ mypy src/blosc2
[...]
Found 170 errors in 8 files (checked 10 source files)
$ 

Static typing annotations are not useful without running a static type checker.

Ok, this is a major task. Will have to be deferred probably after 3.0.0-rc1 which is coming soon.
