Precis-i18n

- Fixed an issue in the Nickname profile implementation that trimmed
extra leading/trailing white space beyond the `Zs`
category prescribed in RFC 8266. Python treats certain
Unicode control characters such as `'\n'` and `'\t'` as white space. If
these appeared as leading/trailing spaces in a Nickname string, they
were stripped. With this release, the Nickname profile will raise a
UnicodeEncodeError `DISALLOWED/controls` if any control
characters are encountered. (Issue 29)
- Update internal tables for Unicode 15.1.
- Add Python 3.13-dev to CI build environment.
- Change format of README and CHANGELOG files to Markdown.
- Drop support for Python 3.3 and 3.4.

- Update internal tables for Unicode 15.0.
- Small type hint fix to one `.pyi` file.
- Add Python 3.11 and 3.12 to CI build environment.
- Update copyright year (2023).

- Update internal tables for Unicode 14.0. These updates also affect
context rules for Unicode 11.0 through 13.0. In limited cases under
previous versions of precis_i18n, valid strings under Unicode
11.0-13.0 were erroneously DISALLOWED due to context reasons
hebrew_punctuation, katakana_middle_dot, and zero_width_nonjoiner.
