Approvaltests

You can now verify html and it will pretty print it. This adds a pip dependency on beautiful soup (bs4)

Breaking Change

verify_file("sample.xml") will produce an approval file with an .xml extension

verify_file("sample.xml",options=Options().for_file.with_extension(".json")) will produce an approval file with an .json extension

Added support for [DiffEngineTray](https://github.com/VerifyTests/DiffEngine/blob/main/docs/tray.md)

verify_as_json` can now take an optional parameter `deserialize_json_fields` which if True will produce nicer formatted output.

json
{
"type": "dictionary",
"value": "{\"a\": 1, \"b\": 2, \"c\": 3}"
}


vs

json
{
"type": "dictionary",
"value": {
"a": 1,
"b": 2,
"c": 3
}
}

Create regex scrubber
Renamed `scrub_with_regex` to `create_regex_scrubber`.
It can now take either a `str` or a `Callable[[int], str]`

Going forward, functions that return scrubber will start with `create` while functions that scrub directly will start with `scrub`
