Multiangle solves don't work in parallel

[eyoung55]

Description

The solver type "multiangle" doesn't work when running WindSE in parallel.

Steps to reproduce issue

Start with WindSE/tests/9-Regression/Yaw_Optimization.yaml, change the solver type to multiangle and add the specification num_wind_angles: 4. Run this modified case with mpirun -n 4 windse run Yaw_Optimization.yaml

Current behavior

Currently this produces a solver error for any wind angles not equal to the initial wind angle. This is directly related to the way boundaries are updated for new inflow angles in serial (using a mesh function and adapting it to the refined grid) which cannot be extended to parallel.

Expected behavior

This code should produce the same result as running in serial.
