🎨 Proper support for static methods that were in v1.x

[Ousret]

Something was not quite right with the v1 support regarding:

• CharsetNormalizerMatches.from_bytes
• CharsetNormalizerMatches.from_fp
• CharsetNormalizerMatches.from_path
• CharsetNormalizerMatches.normalize

This PR provides a better/cleaner implt.
