`stopTimeout` seems to be stopping location updates even if not stopped for full duration

• Plugin config:

// And this one
return bg.Config(
      transistorAuthorizationToken: token,
      showsBackgroundLocationIndicator: false,
      stopOnTerminate: false,
      startOnBoot: true,
      stopTimeout: 4,
)

Expected Behavior

Locations continue to send if I stop for less than stopTimeout. And if I stop for over stopTimeout, locations should get sent again after moving 200m

From the Philosophy of Operation

If any motion is detected before this timer expires, the plugin will remain in the moving state.

Actual Behavior

Taking a short stop prevents locations from being sent. I don't get locations even after 200m+ of movement.

Steps to Reproduce

1. stopTimeout = 4 minutes
2. Move over 200m
3. Stop for 60 seconds
4. Move 200m

Context

I'm seeing high background usage and I'm trying to configure the plugin to spend less time running in the background.

I ran two builds on the same device, one with disableStopDetection: true and the other with it false and stopTimeout: 4.

The one with stopTimeout: 4 used 8 minutes in the background. The one with disableStopDetection: true used 45 minutes.

The only issue, is that the one with stopTimeout: 4 stopped reporting after a short pause.

disableStopDetection: true - you can see the point in the bottom right is further than 200m

stopTimeout: 4
