Coastal change directionality incorrect in some areas of bright sand

@LeoLym encountered an issue where annual coastlines data appears nicely ordered and consistently eroding:

However, the derived rates of change statistics alternative between eroding and prograding (despite this not matching the underlining coastlines):

This is possibly caused by bright oversaturated white sand producing a MNDWI value similar to water, which confuses the analysis step which determines directionality by comparing the "wetness" of the baseline vs. comparison year.

Appears to be resolved in version 1.0.0 due to improved cloud masking
