I came across https://pypi.org/project/liccheck/ and thought we should see what
it reports for Allura. With a .ini file like

- MPL is ok according to https://apache.org/legal/resolved.html#category-b but
should be labelled (in NOTICE or LICENSE)
- `chardet` LGPL is not good.
- we use it directly and requests lib uses it and doesn't intend to change
https://github.com/psf/requests/issues/3389
- chardet won't change their license:
https://github.com/chardet/chardet/issues/36
- alternatives: https://github.com/Ousret/charset_normalizer or
https://github.com/PyYoshi/cChardet (MPL multi licensed?
https://github.com/PyYoshi/cChardet/issues/54)
- another ASF project has discussed a bit at
https://github.com/apache/airflow/issues/10667
- `nose` LGPL is not good
- it is mostly a test runner, but we do import 'nose' modules within our
tests
- should switch to `pytest` anyway since nose isn't maintained
- BSD-derived, BSD-like, ZPL, ISC, HPND are a like BSD/MIT and should be fine
- `feedparser` is BSD 2-clause
