Fixes for pandas 3.0.0 and pvlib 0.14.0

[RDaxini]

Describe your changes

Fix failing pytests and nbval/testbook checks.

Fixes include:

• psm3 calls, e.g to read local psm3 files, manual read_csv function is used now rather than the pvlib read psm3 function that was removed in the latest v0.14.0 release. Note: docs updated
• "H" -> "h"
• units formatting in the o2permeation database, causing some of the tests in test_utilities.py to fail
• material format handling
• use .iloc[0] for positional indexing in humidity tests
• convert strings to objects in convert_tmy
• rerun notebooks
