Frozen Soup is now based

Frozen Soup, my Python library/tool for creating a single-file version of an HTML page got another release that adds handling of <base> and specifying selectors to knock out.

This is another one where I had to re-do the release because of something dumb. This time it was forgetting to bump the version in pyproject.toml. I should look into how to have it automatically figure that out from the tag during release.

Monolith is another project like this that is written in Rust.
