Replace older toml lib with current tomli

[a-detiste]

"tomli" got later merged in the standard library as "tomllib"

Hi @a-detiste!
Are you looking to move to tomli to follow the trend of other projects adopting tomli instead?

The current 2.3.0 version of tomli supports Python 3.8 and later so it's something that's compatible. 🙂

With tomli in the standard lib (since 3.11) sounds like something to keep in mind once 3.10 reaches EoL (Oct 2026).

• Hi,

I ve been patching Debian and submiting patches upstream to remove usage of old libraries for a while

https://wiki.debian.org/Python/Backports

Ultimate goal is to replace tomli completely with tomllib, in a few years, but I try no to confuse upstream projets with PR that try to do too many things at once.

Replacing toml with tomli is a intermédiate step that makes it easier.

The API of tomli vs tomllib are identical

The API of toml not

After this PR the plan is to send a second one to make tomli optional on py3.11

So I m not following a trend per se, rather trying to initiate/promote it 😁
