Create wrapper around *_to_height methods for exposure BHoM-side

[tg359]

Description:

Methods already exist, but aren't (very) accessible via other BHoM tools. Let's make the more accessible!

Search for to_height, or at_height for the methods, with the main one being one that's give an EPW file and translates the entire file.

It might be necessary to add an argument for the file save path for translate_to_height for epw files additionally
