Allow to fix yaw to nominal wind direction #850

This isn't related to the changes in the current PR, but I'm having a hard time understanding what the UncertainFlorisModel does. For example, how are wind speed and TI resolution used? Does uncertainty get modeled for those variables in addition to wind direction? Also, do Gaussian weights get applied to the power at the wd_sample_points? I'd suggest some additional explanation in the class docstring.

This description is a little confusing to me. Could this say "When False, the yaw misalignment is the same across the sampled wind directions. When True, the turbine orientation is fixed to the nominal wind direction such that the yaw misalignment changes depending on the sampled wind direction."

Add fix_yaw_to_nominal_direction
This pull request re-includes the option in the UncertainFlorisModel to fix the yaws into the frame of the nominal wind direction. Currently for example, if yaw angle is 0, and wind direction is 270, uncertainty is computed over a range of wind direction while holding yaw = 0. This pull request adds the flag fix_yaw_to_nominal_direction, which changes the computations such that the yaw is modified to always be 0 relative to the nominal 270 degrees (so it would be +3 when checking 267 for nominal 270)
