Update or replace Pelicanus to be Python 3.10 compatible.
When installing a conda environment with Python 3.10 and installing texta-mlp into it, it will throw an error when import the MLP class due to a deprecation in the collections module that Pelicanus uses.
File "/home/mkollo/.conda/envs/py10-mlp/lib/python3.10/site-packages/pelecanus/pelicanjson.py", line 27, in <module>
class PelicanJson(collections.MutableMapping):
AttributeError: module 'collections' has no attribute 'MutableMapping'
https://docs.python.org/3.8/library/collections.html
Deprecated since version 3.3, will be removed in version 3.10: Moved Collections Abstract Base Classes to the collections.abc module. For backwards compatibility, they continue to be visible in this module through Python 3.9.
