[ENH] Open MPK files in Python/GemGIS

[AlexanderJuestel]

Is your feature request related to a problem? Please describe.
GemGIS should be capable of reading MPK files.

See: https://docs.fileformat.com/gis/mpk/#:~:text=Create%20MPK%20File%20Using%20ArcGIS,-MPK%20files%20can&text=The%20%E2%80%9CShare%20As%E2%80%9D%20option%20in,view%20the%20map%20and%20data.

Describe the solution you'd like

• Using os.rename() to rename .mpk to .zip

import os
file_in = 'file.mpk'
file_out = file_in.split('.mpk')[0]
os.rename(file_in, file_out+'.zip')

• Using ´py7zrandarchive.extractall()` to extract all files

import py7zr
with py7zr.SevenZipFile(file_out+'.zip', 'r') as archive:
    archive.extractall(path=file_out)

• Using os.walk() to go through all directories and list all shapefiles

files = [os.path.join(path, name) for path, subdirs, files in os.walk(file_out) for name in files if name.endswith(".shp")]

• Open shapefiles using GeoPandas and return them as dict with the file names as keys

gdfs = {file.rsplit('\\')[-1]: gpd.read_file(file) for file in files}

Describe alternatives you've considered
Renaming the file manually and open the shapefiles manually

Additional context
No other package was found so far that can do this
