[Chimera-users] Opening Amira segmentations

[Paul Korir]

Shameless plug but as part of sfftk we use ahds to read Amira files. 
It's still in development but the more hands involved the better it will 
get at handling Amira files. It's supposed to be able to read any type 
(AmiraMesh, HxSurface) but it's as good as the examples we have.

Install it from PyPI with pip install ahds==0.2.2.dev0 for the latest 
release that supports Python 2.7, 3.5, 3.6, 3.7. Checkout the 
documentation at 
https://ahds.readthedocs.io/en/v0.2.0.dev0/overview.html#overview

It also has an API for integration into other apps.
