[BUG] Use importlib.resources or encode assets into Python

[sethmlarson]

Describe the bug

The assets/ directory shouldn't use the filesystem directly, instead should use importlib.resources or load the data into Python similar to how the idna package does so.

This is to make charset_normalizer work in situations where there isn't a filesystem available like when being run from a zip file/static binary.

Hi @sethmlarson

Thanks for the report, I have proposed PR #55 that will resolve this case.
