custom hub height

[RLiNREL]

currently, the height settings are limited to the available heights for the dataset, 30m, 40m, etc. Custom height is preferred to users, for example, 59m, 46m, etc.

Feedback from EWT Wind, Trevor, "Our most popular towers are 46m, 59m, 69m and 84m and the fact that we only can select 40 m& 60 m is desinformatie and not that useful for our prospects. If 70 m and 80 m HH were usable options, it would be way more useful."

It is likely to be a linear interpolation between heights that have existing datasets, for example, the wind speed or production estimation at 46m would be interpolated from the nearest 40m and 50m data points. Although, wind direction at custom height would not likely be in the scope, as the physics are complex and may require more research.
