Ensemble configuration QOL

[cnewman]

At the moment, users have to manually comment/uncomment model file paths and python dictionaries to use other configurations of the ensemble. Should make this something that can be done on the command line or a server configuration file. Alternatively, expose an API to use the ensemble without running the webserver.

Potential Plans:

• Allow server configuration files to import models before running flask server. This is pretty easy to do quickly.
• Create a public API that allows configuration via command line. This could take some work since, most likely, people would want/need access to the splitting and feature config functions too.

Model config is now automatically selected based on what model is chosen when the server is run dd4efb9
