Use jinja2 templating to update library to unicode 15.0, #61

- update `tox.ini`, `requirements*` files
  - use `pip-compile` with "requirements.in" files to generate "requirements.txt" files
  - use older testing tools for older python versions
  - ensure for python 3.10 and 3.11
- bin/update-tables.py changes,
  - use jinja2 (`.j2`) templating to generate code and documentation,
    - easier to support code generation of other languages
  - use https and perform retries
  - build cache uses HEAD to compare last-modified for refresh
- `for wcwidth/table*.py` files
  - uses new template system to generate new table data files for unicode version 14 and 15
  - when a description of unicode is single codepoint, describe only as 'A' instead of 'A..A'
