Type annotations

[multimeric]

I rely pretty heavily on type annotations, and I envisage using ro-crate-py a lot in the near future. Would you be open to me submitting a PR that adds type annotations to the library?

If this is okay, could I bump the minimum Python version from 3.7 to 3.9? 3.7 has been EOL for a while, and 3.8 will be EOL just over a week: https://devguide.python.org/versions/. The reason this matters is that it unlocks better type syntax such as list[str].

OK, thank you!

Already done that in #200

@multimeric are you still/yet working on this?

If not: I put some effort into getting type annotations to work for ro-crate-py. I will probably keep working on it from time to time: https://github.com/dnlbauer/ro-crate-py/tree/type_annotations

No I'm not. I made a start which you can feel free to look at, use or copy here: master...WEHI-SODA-Hub:ro-crate-py:typing.

However I ended up developing alternative approaches to this problem, which is why I never finished this.
