Bug: pyproj.exceptions.CRSError for current version of pyproj (2.1.3)

[JSchiefelbein]

Calling example_osm.py with pyproj version 2.1.3 leads to the following error:

Traceback (most recent call last):
  File "/Users/PycharmProjects/uesgraphs/uesgraphs/examples/example_osm.py", line 202, in <module>

Error caused by function latlon2abs() in uesgraph.py:

pyproj.Proj(
                        proj='aea',
                        lat1=lat1,
                        lat2=lat2)

Currently only tested with Mac OS 10.14.4. Seems to work fine for pyproj version 1.9.6.

@JSchiefelbein Thanks for raising this. What is your suggestion to solve this?

This can be resolved by changing def latlon2abs(geometry, lat_1, lat_2): and pyproj.Proj( proj='aea', lat_1=lat_1, lat_2=lat_2)
