Is your feature request related to a problem? Please describe.

The latest phyghtmap release does not work very well with latest Python and matplotlib versions.
Someone forked it into pyhgtmap however wahoomc has a hardcoded binary to phyghtmap.

Describe the solution you'd like

A way to specify the binary, or maybe setting the default used binary to the new fork while having a fallback to the old version.

Describe alternatives you've considered

Currently I just made a symbolic link, pyhgtmap seems to have backwards compatibility and I was able to create a map.

Unfortunately I think it's not Windows compatible yet: agrenott/pyhgtmap#7
