Various small fixes

Describe your changes
Various small changes and fixes, the commit messages should be pretty descriptive.

Related issue
Closes #50, Closes #51, Closes #52
I added the option to pass through all kwargs instead of just lazy. This partially addresses #49 through the fontNumber option. I think the issue should probably stay open though, since I feel like a nicer interface to interact with collections is still needed.

Checklist before requesting a review

• I have performed a self-review of my code.
• I have added thorough tests for the proposed changes.
• I have run the tests and there are no errors. (test_get_fingerprint_diff_between_variable_instances and test_str fail, but they also fail on main for me. Only test_str fails in main for me.)

Okay, seems like 1494afd causes the test failure. Though I am not entirely sure why. I am pretty certain the commit is correct. Should I just drop it for now?

Edit: I adjusted the get_fingerprint() function. I believe all tests should pass now. Though if you would rather I drop both commits, I can do that to.

Thank you very much for this great PR, just that range object optimization and I merge it.

[fabiocaccamo]

a code_range variable could be created outside the loop to avoid range object creation at every loop iteration.

[seproDev]

I changed it to if 0 <= code < 0x110000: which should be cleaner.
