GPS Sensor Support

[Tropix126]

What's the motivation for this feature?

We current lack support for the V5 GPS sensor as provided by vex-sdk.

Describe the solution you'd like

Adding support shouldn't be too bad (it'd essentially be the InertialSensor API but with a few extra getters). We might want to have an Imu trait or something for common functionality to be shared between the two sensors, since their APIs are near identical in the imu-facing hardware abstractions.

Describe the drawbacks, if any

I don't have a GPS sensor to test on. Think Liam does, though, so we could use that.

Describe the alternative solutions, if any

None
