WindIO changed shear specification and python 11 compatibility

[jaredthomas68]

This PR makes a few necessary adjustments to work with H2Integrate

1. In H2Integrate, the wind resource is passed in as a windIO file to Ard, and windIO recently changed the shear specification. This PR updates the shear specification, which now includes both alpha and h_ref in a dict. New tests were also added for the new functionality.
2. There was some string handling in Ard that was not compatible with python 11, this PR updates the string handling to work with python >=3.11
3. Imports were not working when called inside of H2I, so some modules inside Ard were unreachable. This PR corrects the sub-module imports (mostly by removing them) so that Ard imports work from any directory.
