Refurb

This release includes a lot of bug fixes, documentation improvements, the `--enable` flag, and a new check!

The `--enable` flag

This allows for enabling checks which are disabled by default. There are currently no built-in checks which are disabled, but checks in plugins (or future built-in checks) might be disabled by default, and will require you to opt in via `--enable`.

You can also use this via the `enable` field in the `pyproject.toml` file.

The "no del" check

This check warns about the use of a `del` statement which could be rewritten using `.pop()`/`.clear()` instead:

For example, this:

python
nums = [1, 2, 3]

del nums[0]
del nums[:]


Is suggested to be changed to:

python
nums = [1, 2, 3]

nums.pop(0)
nums.clear()
