Discarded start_time for retrieving records from Wyze Scale

[jspalink]

First of all, thank you for this library - this is exactly what I've been looking for for building a connector from Wyze to Garmin Connect.

The start_time isn't passed to the wyze endpoints - instead the entire history is retrieved as the start_time is set here to 0.

You're welcome to submit a PR for things like this that you find. I'm actually about 90% sure that when I coded this, the API wasn't actually honoring a non-zero start_time. I can play around with it a bit and see if that has changed. Or, if you have tinkered locally and confirmed it works, submit a PR and I'll merge and release
