Add DataAPI metadata passthrough to apply

[asinghvi17]

This PR propagates all non-:default style metadata through to the result table in apply on tables, if:

• there is metadata that can be read in the input table
• the result table type supports metadata writes (so not a named tuple table, for example)

This PR also adds GEOINTERFACE:geometrycolumns and GEOINTERFACE:crs tags to the resulting table, and ensures that the CRS is correct according to:
a. the crs kwarg to apply
if that is not present,
b. GI.crs(input_table)

this way, GO.reproject automatically changes the table metadata too!

I should probably PR this idea to GeoInterface too, preferably that gets merged before we merge this.

Nevermind, I already implemented this in https://github.com/evetion/GeoDataFrames/pull/70 so it just works!

Looks good.

It could be nice to put this metadata update function in GeoInterface.jl some day, so we use the same thing everywhere. But here is fine for now.

Agreed, will look at a GeoInterface PR to encode this standard tomorrow. Then we can go about defining metadata for e.g. GeoJSON, Shapefile, etc so everything just flows.
