User importer

[spottseng]

Summary

Provide a brief summary of the changes in this PR and link to the relevant issue(s) if applicable.
There was a circular dependency with using the importer classes, so the logic for uploading the user file and getting the different JSON keys is in the UserAnalytics class now. This also makes it so the user file upload logic can be removed from the MatchAnalytics file, which it should never have been in in the first place.

Current Behavior

Please describe the current behavior that you are modifying.
The user upload was being handled in the MatchAnalytics class, which required an awkward import for MatchAnalytics on the UserPage.

New Behavior

Please describe the behavior or changes that are being added by this PR.
The UserAnalytics class handles the user file import now, and the logic for getting the right keys for accounts and devices is much simpler and cleaner.

The lat and log coordinate data has been commented out for now since it wasn't working super well before and needs a whole new solution.
