TeslaFi import failing on battery level data

[WotAGitUR]

I think I've spotted why new imports from TeslaFi are failing.
When they changed the polling method, the "battery_level" field changed from being an integer to float
So it no longer mostly matches "usable_battery_level"
usable_battery_level would be 57 but battery_level is now 57.35 for instance and the import fails with a "errors: [ battery_level: {"is invalid", [type: :integer, validation: :cast]} ]
Because it's no longer an integer
I opened the files and changed them to integer and the import worked fine
