py-ftfy: updated to 6.1.3

Version 6.1.3 (November 21, 2023)

- Updated wcwidth.
- Switched to the Apache 2.0 license.
- Dropped support for Python 3.7.

Version 6.1.2 (February 17, 2022)

- Added type information for `guess_bytes`.

Version 6.1.1 (February 9, 2022)

- Updated the heuristic to fix the letter ß in UTF-8/MacRoman mojibake,
which had regressed since version 5.6.

- Packaging fixes to pyproject.toml.

Version 6.1 (February 9, 2022)

- Updated the heuristic to fix the letter Ñ with more confidence.

- Fixed type annotations and added py.typed.

- ftfy is packaged using Poetry now, and wheels are created and uploaded to
PyPI.

Version 6.0.3 (May 14, 2021)

- Allow the keyword argument `fix_entities` as a deprecated alias for
`unescape_html`, raising a warning.

- `ftfy.formatting` functions now disregard ANSI terminal escapes when
calculating text width.

Version 6.0.2 (May 4, 2021)

This version is purely a cosmetic change, updating the maintainer's e-mail
address and the project's canonical location on GitHub.

Version 6.0.1 (April 12, 2021)

- The `remove_terminal_escapes` step was accidentally not being used. This
version restores it.

- Specified in setup.py that ftfy 6 requires Python 3.6 or later.

- Use a lighter link color when the docs are viewed in dark mode.

Version 6.0 (April 2, 2021)

- New function: `ftfy.fix_and_explain()` can describe all the transformations
that happen when fixing a string. This is similar to what
`ftfy.fixes.fix_encoding_and_explain()` did in previous versions, but it
can fix more than the encoding.

- `fix_and_explain()` and `fix_encoding_and_explain()` are now in the top-level
ftfy module.

- Changed the heuristic entirely. ftfy no longer needs to categorize every
Unicode character, but only characters that are expected to appear in
mojibake.

- Because of the new heuristic, ftfy will no longer have to release a new
version for every new version of Unicode. It should also run faster and
use less RAM when imported.

- The heuristic `ftfy.badness.is_bad(text)` can be used to determine whether
there appears to be mojibake in a string. Some users were already using
the old function `sequence_weirdness()` for that, but this one is actually
designed for that purpose.

- Instead of a pile of named keyword arguments, ftfy functions now take in
a TextFixerConfig object. The keyword arguments still work, and become
settings that override the defaults in TextFixerConfig.

- Added support for UTF-8 mixups with Windows-1253 and Windows-1254.

- Overhauled the documentation: https://ftfy.readthedocs.org
