Hi @sighingnow,

Thanks for bringing parsec to python!

I have made the following changes:

• feat(Text.Parsec.Char): exposed satisfy from Text.Parsec.Char
• refactor(Text.Parsec.Char): use satisfy accordingly
• feat(Text.Parsec.Combinators): implemented between from Text.Parsec.Combinators
• feat(Text.Parsec.Number) implemented {decimal,binary,octal,hexadecimal} from Text.Parsec.Number
• ci: invoke test via coverage.py and show coverage with missing lines
• ci: perform type checking via mypy
• test: added tests for edge cases in existing code

Feel free to let me know if there's anything you would like to change or if there are any comments.

Best Regards,
Leo
