Updates to openfast_io to match current dev branch API

This PR is NOT ready to merge until TODOs below are cleared.

Feature or improvement description

Updates to the openfast_io library to match the current dev branch API. Once merged, will provide OpenFAST users with an up-to-date library that they can import to read/write OpenFAST files. This follows the fst_vt nested dictionary structure developed under WEIS and heavily borrows code from there.

This library is currently limited to OpenFAST and does not work with FAST.Farm or any of the module drivers.

Test results, if applicable

pytest added to span most OpenFAST input files (drivers not included). Based on @andrew-platt comments in #2233, need to introduce automated testing.

TODO:

• Add test automations & GH actions
• Create an OpenFAST PyPI account so the openfast_io python package can be installed with pip
• Set up a trusted publisher to securely upload the python package to PyPI
• Setup conga-forge for openfast_io since most NREL tools like WEIS and WISDEM prefer it.
• Check if we can eliminate the Poetry file We will continue using Poetry
• Add additional tests based on recommendations in this PR if any
• Address old API warning thrown by AD15
• Add simple documentation to help users get started
• Add badges for PyPi and conda-forge

I haven't checked through the code, but just noticed there is a new input in the AeroDyn input file that wasn't included in any of the regression tests yet (adding that line to all AD input files in PR #1295).
