Add a kwarg to set OSRAxisMappingStrategy

[rafaqz]

This is a first pass at setting OSRAxisMappingStrategy with a keyword argument.

I'm not sure how to implement it for fromWKT etc methods, where the @gdal macro is used, so some input on that would be helpful.

But otherwise it works for reprojecting points.

The default is :trad now for testing, but we can change that to :compliant depending on what people want the default behaviour to be for ArchGDAL

closes #119

[rafaqz]

This is now just reproject, importCRS and newspatialref. :compliant is the default so that nothing changes fro current behaviour unless users specify :trad in either of those methods.

Also ready to merge.

Can we update https://github.com/yeesian/ArchGDAL.jl/blob/master/docs/src/projections.md with documentation on GeoFormat and these changes as well?

Your comments are resolved and code/docs are cleaned up.

I barely have time to do this PR currently, I'm not sure when I would be able to do that.

[rafaqz]

Can you merge this?

[yeesian]

Thanks! Yeah the documentation is not a blocker, thanks for the ping!

[rafaqz]

Actually good you waited a while as I found those extra bugs in the meantime :)

[rafaqz]

Oh can we get a release as well? Trying to get GeoData.jl published.
