Load/save CRS information

[juliohm]

Now that the stack supports CRS, we need to account for that in some file formats.

Now that JuliaGeo/GeoParquet.jl#25 is merged, we can address this issue.

@eliascarv do we have all the ingredients in place to complete this issue?

[eliascarv]

Yes, now you just need to get the EPSG code from ProjJSON.

[juliohm]

Apparently our asgeotable function already extracts the CRS from the table:

GeoIO.jl/src/utils.jl

Line 13 in ad420fc

crs = GI.crs(table)

I tried with a couple of sample files, and they still load the CRS as Cartesian{NoDatum}.

Now, the only thing left is to parse the GFT.GeoJSON object in the crstype function.

Thanks for adding the missing projjson in #146 . I didn't check the save part of this issue yet, but please feel free to close it if it is already addressed.

[eliascarv]

PR #146 only adds support for loading ProjJSON.

Fixed on the master branch.
