Hi,

When working with git master branch, or 3.32.2, QGIS Azimuth and Distance plugin seems to add a constant offset to the azimuths entered.

I am working with projected CRS EPSG:22717 NAD83(CSRS) epoch 2010 for both project and point layer.

I add to Active layer, using Survey type Boundary, Angle type azimuth or bearing, Distance unit Default, Angle unit Degree, North type Default.
I choose a point on the map, and create a segment 100m Azimuth 0, then Draw.
If i use the measure bearing tool, i get around 0.32 degrees, and it seems to vary slightly each time i draw from a different starting point, but if I delete the drawn, point and snap to the same starting point, i get the same offset.

I've opened an issue here: https://github.com/mpetroff/qgsazimuth/issues/32

I took a brief look at the code and I don't see anything adding an offset that shouldn't, but I'm new to GIS so maybe there's something about using a projected CRS that I'm missing.

It seems to me if I draw something with a certain bearing, the Measure Bearing tool should give me back the same thing.
