Direct data transfer for AeroDyn inputs

[kevmoor]

Currently it uses the file based system and the files are automatically generated, should change to use the direct passing of that data and avoid the file i/o. This is low priority and impact though since it only happens at startup.

This has been changed since OpenFAST direct string passing is being depreciated and only the file input options are being supported going forward, so all of the direct string passing options need to be replaced with a process where a template file is pulled in, modified, and exported, then the library told to use that file. An example of this is done in OWENS.jl for the turbsim input file when the DLC run is active.
