Support of http access

[alex-s-gardner]

It would be nice if GeoJSON.read() could accept a URL, e.g. "https://its-live-data.s3.amazonaws.com/datacubes/catalog_v02.json"

I'd just use HTTP separately, it only adds one line of code:

using GeoJSON, HTTP

resp = HTTP.get("https://its-live-data.s3.amazonaws.com/datacubes/catalog_v02.json")
fc = GeoJSON.read(resp.body)

Otherwise we'd have to take on a dependency on HTTP.

Ya, that makes sense. I got lost with trying:

resp = HTTP.get("https://its-live-data.s3.amazonaws.com/datacubes/catalog_v02.json")
fc = GeoJSON.read(resp)

Maybe I can add an example to the ReadMe

[visr]

Yes that'd be welcome!

I just create a pull request #90 so that we can use Downloads.download in stdlib

using GeoJSON, Downloads
io = Downloads.download("https://its-live-data.s3.amazonaws.com/datacubes/catalog_v02.json", IOBuffer())
fc = GeoJSON.read(io)
