+ Implemented register, find, and add_location
+ Bunch of changes to the DB and the Models to make this work
+ API models are defined in GeoffreyModels so things that call the API don't need to define their own types
+ Still needs a lot of work, and need to design the api a bit more
+ Clippy + fmt
+ Fixed issue where IDs of different models were colliding
+ Used built in methods to convert u64 to bytes
+ Added tests for database speed
+ Converted return time of filter to an iterator
+ Added better error handling for non-unique values
