- Adds additional functions for computing energy ratio as a function of wind
speed
- Adds an example which uses FLORIS simulation to demonstrate the energy ratio
methods

Wake Model changes

- Set deflection multiplier in gauss deflection to 1.2 (was 1.0) to better
match SOWFA and field results
- Update regression test to match

Small Changes

- Removal of unnecessary imports in some files
