Update demo datasets

[Dev-Lan]

Loonsw url should have:

• double check quil datasets (cleanup name)
• example from loon (https://loon.sci.utah.edu/detailedView/Example_MCF7)
• aardvark examples, see image (https://aardvark.sci.utah.edu/)

1. Test Locally:

• Clean up name of quil dataset
• Clean up name of locations to be string names.
• Test location switching and app performance

2. Deploy to app:

• Log into server, edit relevant files, reboot Loon
• Test location switching and app performance
• Include two more datasets: Example MCF7, and Aardvark Dataset mentioned above
  • Aardvark dataset
  • loon_example_data (Example MCF7) 74GB

I'm testing locally to see if I can change the location names for the quil dataset (aka can we accept strings instead of numbers for imaging locations).

Creating a branch / PR to accept a 'name' param for imaging locations to serve as the user-facing-name of the imaging locations, rather than a number.
