pylandau 2.2.1

This release adds support for numpy 1.21 since 1.22 is not supported by numba (yet). Before, pylandau dependencies and numba dependencies could not be resolved if both packages are installed.
From now on, the C code will be compiled at installation to build against the specific numpy version the user is running.

What's Changed

• Numba support in pylandau environment by @cbespin in #23
