Feature or improvement description
Implemented analytical calculation of dudz_initial based on the power shear law to enable GCH model usage with only 1 turbine grid point.

Related issue, if one exists
None.

Impacted areas of the software
flow_field.py, solver.py, wake_deflection/gauss.py

Additional supporting information
Currently, the solution does not account for vertical gradients induce by heterogenous wind definitions. The assumption is this contribution would be relatively small in most cases and can be neglected.

Test results, if applicable
Regression values need to be updated.
