Move polar alignment helper functions into POCS images utils

[wtgee]

The polar alignment features aren't used in PIAA, they are only used in pocs_shell, so this is more appropriate.

However, this was mainly done because of the order in which some of the new files were loaded, causing the logger to emit before the new log adapter (from #254) can be loaded. By loading from pocs/utils/images.py that loading ordering is fixed. Closes #263 and #264.
