Rotation bugfix

[pcuste1]

Description

This PR addresses two bugs that have been found related to the orientation plugin

1. Sets the value of self.rotation_angle with the orientation plugin when a new orientation is set. This wasn't being done before, and thus aida was unable to determine the orientation of imviz properly.
2. Whenever aida creates a new orientation, it first reverts back to Default Orientation to ensure that the least number of updates is needed for the new orientation. This adds a slight lag to adding new orientations for orientations < 4 but significantly reduces lag when any more orientations are created.

Note: still outstanding is the issue of setting self.rotation_angle when the orientation is changed to an existing orientation. That will need to be addressed in a separate PR once a root cause is determined

would it be possible to just grab the default orientation when creating the new WCS-only layer and rotating on top of that without actually changing the selection? That would avoid the need for the viewer to "flash" between.
