Add 2 notebooks:

  1. Process measured turbine data - perform bootstrapping to get descriptive statistics.
  2. Compare turbine models - generate all plots related to turbine outputs

1. Process measured turbine quantities (50Hz resampled to 1Hz, then
   perform bootstrapping to get descriptive statistics)
2. Process modeled turbine quantities and compare across all models
- process thrust in addition to other quantities
- correctly estimate generator power for rotor power if unavailable or
  recorded as nan
Note that not all participants that provided power data had thrust data
available
E.g., multiple DWM results, using simple mean
- vertically center labels
- consistent bar heights
Interpolated values are scaled by the density recorded at SWIFT divided
by the OF simulated density (i.e., `AirDens` in SNLV27_AeroDyn15OF2.dat)

Thrust values are converted from N to kN
If generator torque data are unavailable but rotor aerodynamic torque
is, then estimate generator torque from the gear box ratio
CT processing required special treatment for some participants;
unrealistically large CT were set to nan (with an ad hoc cutoff of 5)
- updated plot order/colors
- revert to default xlim for neutral thrust plot
- output at 300 dpi
- plot openfast-predicted power
Luminosity method is most reliable for determining the grayscale value,
then (1 - grayscale_value) gives the opposing color. To maximize
contrast, round up/down to white/black.
Normalized by openfast-predicted power as reference
