Feature request: interpolation options in extract

[alex-s-gardner]

When using extract to retrieve point values from a Raster it would be useful if the user could specify an interpolation option.

Where would the interp algs come from

Where would the interp algs come from

I think the best option is Interpolations.jl

I just had an idea to do this lower down in DimensionalData.jl. Like have an Interp selector that returns an Interpolations.jl interpolator thing.

You could do thing like rast[X=Interp(x, Spline()), Y=Interp(x, Linear()), Ti=Near(DateTime(2020)))] and it would just work.

Then extract could just call this.

That would be ideal
