CE-Symm 2.3.0

Fixes determination of the order, symmetry group, and axes of CE-Symm alignments. Results with small symmetry units (<15 residues) are particularly improved. The CE-Symm minor version has been bumped to reflect the different results.

Java 11 or higher is now required to run CE-Symm and QuatSymm.

This version also includes updates to the underlying biojava library, including updates to main compatibility with RCSB and other resources.
