Impacted areas of the software AeroDyn

Test results No change expected as this introduces new options, and the input file is read as backward compatible.

• [x] Finish pull request
• [x] Make sure connections for the Shear weighting is done
• [x] Document changes - Live doc here
• [x] Add example file , here

Future pull request

• Change all the r-test input files
• Add aerodyn test case for new features

This pul request is ready for review. Becasue it relies on dev-unstable-pointers, I would like to recommend merging it now at this point, so that others start to use it and potentially give feedback / bug fixes. The implementation is currently backward compatible and tell the user how to change the inputs.

In a future pull request, I can work on a script to convert the AeroDyn input files and do that for the r-test inputs.

@ebranlard, if/when you are done with the minor updates, I will plan on merging this in the next day or two.

I've added a small converter for AD3.x to AD4.0 in the openfast_toolbox:

from openfast_toolbox.converters.versions.aerodyn import ad30_to_ad40
ad = ad30_to_ad40(fileold, filenew)

See example here.
