brip 0.2.2

• Starting from version 0.2.*, brip changed its project name on PyPI. Now you install it by pip install brip. (If you need to upgrade from the old 0.1.0 version, please run pip uninstall brython-brip first.)
• The brip 0.2.0 and brip 0.2.1's dependency on pip 21.1+ caused unnecessary trouble while installing on Windows. We choose to drop that dependency since this patch release.
