Wonderwords

Added

- Added `CHANGELOG.md`.
- Added custom word categories.
- The Rich library is now an optional dependency.
- Bumped dependency version numbers.
- Added a list of profanities.
- Refactored code.
- Removed profanities by default.
- Added singular forms of categories as default such as "noun" instead of
"nouns".

Changed

- Changed the implementation behind the scenes. Now, word lists are loaded once
and reused between instances of the `RandomWord` class. This is more
efficient.
- Changed the implementation of `RandomSentence` to make up for the changes in
`RandomWord`.
- `RandomWord.parts_of_speech` will soon be deprecated.
- The `include_parts_of_speech` argument for RandomWord methods will soon be
deprecated. The alternative is now `include_categories`.

Added

- Added the regex word matcher for both the CLI and the `RandomWord` class.
- Added "Prerequisites" section to the install page.
- Added sphinx-copybutton to the documentation so that it is easy to copy code
snippets.

Fixed

- Fixed incorrect code snippet in docstring.
- Fixed broken link in documentation.

Fixed

- Added dependencies to `setup.py` (somehow completely forgot), fixing the
dependency issue.
- Fixed incorrect commands in the CLI documentation.
- Fixed broken link in the CLI.

Changed

- Refactored the `RandomSentence` class (usage stays the same) in order to be
more modular by introducing the `_present_tense` function.

Fixed

Added
- The `RandomWord` class which offers:

- A documentation on Readthedocs.

Changed
- Changed the command line interface to be more efficient and styled it with the
help of Rich.

class.
