Add physiology data for the species Cat

[msevestre]

see Open-Systems-Pharmacology/Forum#66

This would be a great contribution from the community to the open source platform.

if someone is interested in contributing to this feature request, I could definitely help defining which parameters are required

Not cats, but in general, is there a "how-to" that helps you along the way (file/database format required, also json?)
Same for integration of a new population...

Based on the data from Open-Systems-Pharmacology/Forum#953 cat was created as a copy of beagle in the first step. Now cat-specific parameters must be set, which are summarized in the table below:
