gts encoder conversion
MVELEVATIONS function extracts elevations from an input Geo Time Series™ or GTS Encoder, correctly interpreting Multivariate (MV) values. The result is a potentially multidimensional list.
When a tick has an associated Multivariate value, the
MVELEVATIONS function will emit a list with two elements (a pair), the first element will be the elevation associated with the tick at which the Multivariate value was encountered, the second element will be a list containing the elevations of the Multivariate value itself.
If a tick has no associated elevation,
NaN will be emitted.
