Incompatibility between astropy 5.0.1 and agnpy 0.1.8 ?

[garciagenrique]

Hi, I found and error when installing agnpy from pip, that brings the latests version of astropy (v0.5.1).

When importing agnpy it raises the following error (see below). I downgrade astropy to 4.2 and agnpy can be imported correctly.

     10 except (ImportError, ModuleNotFoundError):  # optional dependency

ImportError: cannot import name 'Annotated' from 'typing' (/opt/conda/lib/python3.8/typing.py)

During handling of the above exception, another exception occurred:

Thanks @garciagenrique, I will look into it.
