Add endpoints for changing device location (#188)
Added GenericResponse struct to have a single interface that can be used to return both errors and meaningful messages where applicable, instead of generating JSON on each spot with gin.H or whatever. If you are okay with this I can later update the existing functions
Added endpoint to change the current device location by latitude and longtitude query params
Added endpoint to reset the device location to the actual one
Bubbled up an unhandled error in my own code for device location simulation
