renaming of 'bin_inlet_state' as 'Inlet_state'

[mewilliams]

If you run the post-process check section #5.3 in InletTracker_master.py, check_inlet_state_detection changes the column 'bin_inlet_state' to 'Inlet_state' (if you run #5.3 in InletTracker_master.py), but plot_inlettracker_resultsV2 is looking for 'bin_inlet_state'.

I think the easiest edit be to change 'Inlet_state' back to 'bin_inlet_state' line 1769 of InletTracker_tools.py.

Thanks Megan, I'll try to incorporate that in an update that I'm about the do on the repo.
