QHY driver assumes filter wheel is in position 1 at start, even if it is not.

Using QHYCFW3 with QHY533M. The filter wheel is plugged into the camera (not USB).

To reproduce, set the filter wheel to any position except for 1. Restart INDI driver. I restart the entire profile using INDI Web.

The filter wheel will still be in the physical position it was in, but the driver will report position 1.

To work around this issue, I need to move the wheel to any position after restarting for the driver to be in sync with the wheel again.

Expected results:

The driver should not assume position 1 at start.

There is an updated QHY filter wheel firmware. This firmware is intended to address an issue where dust (and therefore flats) are positioned differently due to backlash. Their fix was to make it such that the filter wheel always rotates in the same direction instead of rotating forward or backward depending on the shortest path to the next filter.

This firmware behaves slightly differently in regards to this bug. The INDI driver still incorrectly reports position 1 on restart regardless of what position the filter wheel is in. However, if you tell it to move to position 1, it does so even though the driver is already reporting position 1.
