[Tudyx]

As stated in RFC 5280§4.2.1.12 in

Key purposes may be defined by any organization with a need. Object
identifiers used to identify key purposes MUST be assigned in
accordance with IANA or ITU-T Recommendation X.660 [X.660].

This corresponds to the other variant of the x509_parser::extensions::ExtendedKeyUsage

This PR add support for others oid in the extended key usage.

It needs to be rebased on main and then I think the "Check semver compatibility" CI task failure will resolve and it could be merged.

[stormshield-gt]

I think the "Check semver compatibility" job won't resolve because this PR indeed add a variant to a non-exhaustive enum. As we have already breaking change in the main branch, I think it's fine.

[cpu]

I believe it will resolve because main incremented the crate version to 0.13.0 alongside introducing the breaking changes. Since that version isn't released, adding more breaking changes won't trip the semver checks.
