Make the package typed

[RubenVanEldik]

This PR adds typing support for logtail. This allows other repositories to use the type hints from logtail. Because Mypy does not support Python 3.7 anymore I removed this form the supported versions, there is currently only 1 downloader per week that uses Python 3.7. I also added support for Python 3.12, as this version is already over a year old.

Hey I'd like to bump this issue.
For anyone wanting quick bypass/fix you can put this in pyproject.toml:

[[tool.mypy.overrides]]
module = ["logtail.*"]
follow_untyped_imports = true
