tilt values from spreadsheet not converted into network json files

[kt-simpson]

Describe the bug
I noticed the tilt values in columns F and L of the Eqpt sheet were not converted into the "net_save_fr_path_requests" and "raw_save_fr_load_common" json files.

To Reproduce
Run transmission_main_example using excel as input with tilt values populated to non 0 values
Result: tilt_target values in resulting json files will be at the default value of 0

Expected behavior
Should populate values from spreadsheet into tilt_target fields

Additional context
I was able to resolve the issue by modifying two lines in convert.py as shown below:
Ln 670 changed 'tilt': 'east_tilt', to -> 'tilt': 'east_tilt_vs_wavelength',
Ln 677 changed 'tilt': 'west_tilt', to -> 'tilt': 'west_tilt_vs_wavelength',

This may not be a proper solution but should hopefully highlight the root cause
