Tidy up and remove dependencies

[pjrobertson]

This removes certain dependencies, seen as unnecessary or unused.

Removed dependencies

• argparse: built into python by default on>=3.2, we only support python3.10+ so don't need the separate (outdated) package. Ref: https://pypi.org/project/argparse/#description
• minify_html: incompatible with python3.13+, although a fix has been merged, it hasn't been released yet. We'll do away with minifying the html as a nice to have
• tiktok-downloader: currently broken (the --snaptik option seems to work, but getting '--info' doens't seem to work) - also removes a lot of other things like flask, aiohttp etc.
• toml it was unused. If we need a toml parser we can use tomli - what's used by pytest, autopep8 etc.

Other dependencies not removed:

• asn1crypto - used by timestamping_enricher but hasn't been updated in 2 years. A possible replacement is asn1
• webtrix crawler - part of a bigger refactor/rewrite. As discussed, can we remove this for something more lightweight?
• tqdm - used by the telethon archier to show progress
• tsp_client - as mentioned elsewhere, it has issues with the latest pyopenssl, and throws warnings on higher versions of python. Currently works, and the dev seems (fairly) responsive. An alternative is rfc3161-client

Looks good! I added a comment to clean up the tiktok_downloader references at some point, but it as is it still seems to fail as expected and default to a backup.
