Updated example yaml files to work with latest Hercules version, plus minor bug fixes

[jfrederik-nrel]

• Updated the yaml input files to work with the latest version of Hercules, replacing the no longer existing component_type Wind_MesoToPowerPrecomFloris.
• Cleaned up examples/simple_hybrid_plant/plant_power_reference.csv to remove redundant entries.
• Changed unit in the label on x-axis of the single_turbine_flexible_interconnect example to mins instead of s.
• Improved theramp_rate_limit implementation in WindFarmPowerTrackingController. This still needs more attention though, tagging @misi9170 for that.

Thanks @jfrederik-nrel !

I've added a few things to this PR:

• Fixed the ramp rate limitations in the wind farm power tracking controllers---thanks for identifying the problem there! I reorganized the code a bit there so that the ramp rate limit could be applied in both the PowerTracking and Distributing versions of the controller. I still need to add tests though.
• Added the noisy_wind_input.csv file needed to run the single_turbine_flexible_interconnect example
• Reverted the x-axis label you mentioned, since I think seconds is the correct unit (even if it's not necessarily realistic); however, I think this was in the wind_farm_power_tracking example rather than the single_turbine_flexible_interconnect example

I'll work on the tests, and then we should be good to merge this if you're happy with the changes I've made.

Test now added, and documentation slightly updated to reflect ramp_rate_limit option in the wind_farm_power_tracking example.

@misi9170 I have reviewed the changes, and have no further comments. I think this pull request can be merged now.
