add DE-9IM predicates and test

[rafaqz]

@evetion these might help with https://github.com/JuliaGeo/GeoInterface.jl/issues/106

There are a few more to add, we have intersects, within, contains, union and intersection so far.

In GeoInterface we can just do things like

within(geom, ext::Extent) = Extents.within(GI.extent(geom), ext)

Yes to disjoint and overlaps, and I guess equals.

Also to very clear tests and docs. This package should be bomb-proof.

But not sure when I will be able to lift it to that standard.

@evetion I went all out ISO and implemented DE-9IM

Seems to work well but some feedback would be good. I'm not sure about the strict keyword and generally what to do as the default when there is an extra dimension in one of the extents (like there is a time or Z dimension in a spatial raster as well as X/Y - what do when checking if it intersects with a regular X/Y raster.

They all seem to take a few nanosecond. I'm thinking we can use them in fast loops over many geometries, matching some predicate like everything that might overlap.
