minor clean-ups to floris.py

Floris wrapper clean-up

Previously when using floris to simulate the wind farm, it would write the wind resource data to speed_dir_data.csv. This file is never read or used anywhere else in the code - so this has been removed. All other relevant information for this PR is found in the below section.

Note: this also includes a patch fix for building readthedocs (see more information here)

Related issues

Impacted areas of the software

• hopp/simulation/technologies/wind/floris.py
  • value(): fixed the set_value functionality to work as documented
  • execute(): cleaned up how operational losses are applied and to only print 'Simulating wind farm output in FLORIS...' if verbose is True (verbose is a new attribute which defaults to True)
  • parse_resource_data: removed part that exports wind resource data to speed_dir_data.csv (this was unused and does not impact the functionality at all)
