New module @turf/interpolate

[morganherlocker]

Takes a set of points and estimates values on a grid.

@DenisCarriere this seems a lot similar to the "validation" step we tried to add inside isobands (random points to grid).
In order to reduce the complexity of that module, which should only do one thing, what if I implement this one and we keep the input of isobands (and isolines) as pointGrid, since this module will be available?

👍 @stebogit Sounds like a good idea.

Many of the "complex" modules usually have 3-4 modules that can be discovered/created prior to making the main module (ex: isobands in this case).

Just to make sure we are on the same page about what this module should do.
My understanding is, based for example on isobands and isolines input requirement, to take any set of points with an elevation/z value and transpose them to a pointGrid, interpolating said "vertical" value on the grid.
Is that correct @morganherlocker and @DenisCarriere ?

[DenisCarriere]

👍 Sounds right to me.
