Read damping from beamdyn input files (#349)

* Set types on wrap functions

* Update IEA-15 inputs

* Update installation instructions -- draft

* Change to new AF Coords

* Fix IEA15 airfoils again

* Try latest setup_fortran action

* Add UAStart/End location writing

* Try intel-classic compiler

* Add developer docs about api changes

* Try macos-latest in CI

* Add support for reading daming from beamdyn blade files (#328)
