Class Parallelogram

Implements the parallelogram primitive for reconfiguration. See https://doi.org/10.4230/LIPIcs.SAND.2026.11.
The reconfiguration of an parallelogram where only the two sides incident to an obtuse corner are occupied by amoebots to a configuration where the other two sides of the parallelogram are occupied.

The algorithm applies two shearing operations on the first (shorter side length + 1) amoebots starting from the outer ends and requires two rounds to complete.
