🐛 `NameError`: name 'TYPE_CHECKING' is not defined

[Marnik Bercx]

Ran into another test failure when trying with the latest abipy develop branch, see:

https://github.com/aiidateam/aiida-common-workflows/actions/runs/5925589563/job/16065306425?pr=314

The error is the following:

/root/.aiida_venvs/w2k/lib/python3.8/site-packages/abipy/tools/typing.py:12: in <module>
    if TYPE_CHECKING:  # needed to avoid circular imports
E   NameError: name 'TYPE_CHECKING' is not defined

The relevant lines are:

abipy/abipy/tools/typing.py

Lines 9 to 19 in d4dd68e

 from pymatgen.util.typing import * 
  
  
 if TYPE_CHECKING:  # needed to avoid circular imports 
     from matplotlib.pyplot import Axes 
     from matplotlib.figure import Figure 
     from abipy.core.kpoints import Kpoint 
 else: 
     Axes = Any 
     Figure = Any 
     Kpoint = Any 

I'm assuming a direct import or TYPE_CHECKING from the standard library module should do the trick, will give it a try and open a PR.
