This PR along helps the user to unload MoorDyn input files for FAST.Farm using PR #40 in openfast toolbox from MoorPy object to allow FAModel to generate FFarm input files.
Purpose
It addresses the need to have fairlead positions defined in the 'unrotated' local reference frame of the platforms. FFarm, then rotates the fairlead based on the ElastoDyn inputs. These examples show two cases with two turbines having different headings. The red lines are the MD input information (before rotation) and the white lines are after applying ED rotations to the farilead connections.
Main changes:
Allowing unload to have platform headings to unrotate turbines such that MD output file has fairlead points in the local unrotated reference frame.
Allowing optional MD dictionary to be an input by the user (if not given, default values will be used) [to facilitate dynamic relaxation anlaysis].
