issue with pyproj and DLL failure on Windows / installation with PIXI

[tjschuckiau]

I was experiencing issues installing the new version of MSS in a conda environment on windows 10 with Python 3.11.9
the error that occured resulted from the following import statement:

from pyproj import _network

File "(...)\envs\mssenv\Lib\site-packages\pyproj\network.py", line 10, in
from pyproj._network import ( # noqa: F401 pylint: disable=unused-import
ImportError: DLL load failed while importing _network: Das angegebene Modul wurde nicht gefunden.

I found a recommandation to fix this by installing Latest Microsoft Visual C++ Redistributable Version which did not work for me.

Installing only pyproj in a clean conda environment did work, also the above imoprt statement did work thereafter. As soon as mss was installed in addition, the above error occurred.

ReimarBauer suggested the following solution which worked fine for me:

Installing pixi for windows (https://pixi.sh/latest/) in windows powershell (as admin) and use pixi to install mss

iwr -useb https://pixi.sh/install.ps1 | iex
pixi global install mss

Starting MSUI now works as follwos:

• open windows powershell as admin
• execute command msui
• IMPORTANT after a second hit 'enter' a second time
