Eml-parser

Changes
- Remove obsolete methods.
- Rework hashing wrapper methods.

Added
- Add a custom e-mail parsing policy for fixhing invalid values as soon as possible.
- Currently implemented for invalid message-id and date parsing.

Changes
- Renamed eml_parser.eml_parser to eml_parser.parser to make imports safer. This should not break any usage but nonetheless
make sure to verify that you are not importing eml_parser.eml_parser.
- While adding tests for Python 3.11, cchardet fails to install. Turns out it seems to be abandoned and as such it has been
replaced with [charset-normalizer](https://github.com/Ousret/charset_normalizer).
- Migrate setup.cfg to pyproject.toml

Fixes
