add pre-commit config

[KrisThielemans]

Copied from https://github.com/SyneRBI/PETRIC/blob/main/.pre-commit-config.yaml, but deleted mypy as yardl generates files that throw up errors with mypy and is using pyright instead.

Obviously, this will change formatting in various files, which we'll need to commit.

I had a quick look at adding

- repo: https://github.com/microsoft/pyright
  rev: 1.1.388
  hooks:
  - id: myright

but that fails with

$ pre-commit run --all
[INFO] Initializing environment for https://github.com/microsoft/pyright.
An unexpected error has occurred: CalledProcessError: command: ('/usr/bin/git', 'checkout', 'v1.1.388')
return code: 1
stdout: (none)
stderr:
    error: pathspec 'v1.1.388' did not match any file(s) known to git.
Check the log at /home/sirfuser/.cache/pre-commit/pre-commit.log
(prd) sirfuser@vagrant:~/devel/PETSIRD$ pre-commit run --all
[INFO] Initializing environment for https://github.com/microsoft/pyright.
An error has occurred: InvalidManifestError: 
=====> /home/sirfuser/.cache/pre-commit/repoa021nr1x/.pre-commit-hooks.yaml is not a file

In any case, this is likely to fail on a bare repo anyway, as the types are only available after generation.

I have no idea if changes are required in the devcontainer.

[KrisThielemans]

Are settings in https://github.com/ETSInitiative/PETSIRD/blob/main/.devcontainer/devcontainer.json independent of this? (That'd be a pain). (Possibly also relevant microsoft/vscode-python#10165)

Once done, I suggest we use https://pre-commit.ci/
