New pip/conda release

Hello,

Thanks for the new fix of numpy and shapely; when will the new version be available in pypi?

ShapelyDeprecationWarning in graph.py

There's a new ShapelyDeprecationWarning in graph.py that will cause an error in Shapely 2.0. Not sure why it appears and therefore didn't find a way to fix it.

vresutils/graph.py:529: ShapelyDeprecationWarning:

__len__ for multi-part geometries is deprecated and will be removed in Shapely 2.0. Check the length of the `geoms` property instead to get the  number of parts of a multi-part geometry.

I think the warning appears somewhere here: https://github.com/FRESNA/vresutils/blob/master/vresutils/graph.py#L528-L530

Resolving permissions in decorator.cachable is broken

I mistakenly introduced the [0] back when I added the fallback_cache_dirs (80c9997). In some intermediate state cache_dir was a list of cache directories and then you wanted the first one from the list.

Varonoi partitioning with few points generates empty areas

Dear developer,

when working at the issue pypsa-meets-earth/pypsa-earth#99 , I noticed that when applying the voronoi partitioning with few points in the shape the result was the one shown below.

That was due to the limits in the size of the voronoi shape that was limited to the size of the points (with a multiplier), while the outline shape was not considered.

Shortly, I post a Pull request to solve the issue.

yaml.load in vresutils.snakemake.MockSnakemake returns warning

When using MockSnakemake I get the following error:

YAMLLoadWarning: calling yaml.load() without Loader=... 
is deprecated, as the default Loader is unsafe. Please read 
https://msg.pyyaml.org/load for full details.
  self.config = yaml.load(f)

As written in the PyYAML doc, there has been filed a CVE against the module. So I would suggest to change line 38 in vresutils.snakemake from self.config = yaml.load(f) to self.config = yaml.save_load(f).
