Add even more units

[Pint](https://pint.readthedocs.io/en/stable/) has a lot of unit aliases defined [here](https://github.com/hgrecco/pint/blob/5e59f373ea237a95f22960a2b169c3a756a264c9/pint/default_en.txt).

Perhaps we could extract the relevant parts of this .txt into your simple .yml format and add them to this package.

Start by comparing Pint's linked default_en.txt with the package's existing simple YAML unit definitions. Identify the relevant aliases and determine how the YAML is loaded by UnitParser.jl. Done means the selected aliases are represented in the package format and can be parsed successfully; no test file is named in the issue.
