`WriteModuleLinearMatrices` is general and can be called by all modules that have linearization routines.
This allows more memory to be allocated when writing the binary file (because we've deallocated things when closing the individual modules).
also fix some comments
Since the trim solution seems to always converge on the first step when NLinTimes == 1 (see OpenFAST#857), I added a warning and overwrite NLinTimes to be 2 instead. This should be removed when OpenFAST#857 is fixed
Note: This does not yet have the changes for AeroDyn in it.
- update ideal beam cases to run in single precision - don't build controllers for linearization cases - update some documentation
Update the rest of the OpenFAST "InflowOn..." inputs to AeroDyn

I tested the code and it works great. Potentially |
- remove comment lines that look like git merge conflict lines - move some SS parameters to FAST_Types (though that didn't solve the issue) - change extension on aero map input files from ".inp" to ".dvr".

Feature or improvement description
Envision Energy and NREL collaborated to add capability to generate aerodynamic maps using OpenFAST. This feature computes a steady-state solution with AeroDyn (15) and ElastoDyn, using the following functional requirements:
To run this new feature, you will need to call OpenFAST with the
-steadystateflag:and will need a new input file for the steady-state driver. An example input file is found at ./docs/source/user/aeromap/examples/AeroMap.dvr
Related issue, if one exists
This is a follow-up to #1631 and #1715, which added the module-level changes for this feature.
Impacted areas of the software
Linearization, particularly in AeroDyn, ElastoDyn, and BeamDyn modules.
Additional supporting information
The BeamDyn aeromaps have not been verified. There is a warning if you choose to use BeamDyn with the aeromap feature, but it will attempt to run and possibly give incorrect answers.
Test results, if applicable
A new
5MW_Land_AeroMaptest has been added to the regression testing. Example plots from the new test are shown below. Note that this is a very coarse model, used for testing purposes only:
