Increase upload dataset limit

• Upload file larger than 250 MB using the binary buffer

• Re-construct string or JSON from the binary buffer

Perhaps stream instead?

Piggybacking on this thread because it seems relevant but I can open a separate issue if needed. The remote map upload fails on json files larger than 50MB because of this error: d3/d3-fetch#34 A solution is to cut out d3-fetch and use just fetch and FetchSteam instead (similar to @stevenroussey-privicy 's suggestion).

Any updates on this!! Can't map national zips because the geojson is too big. (1.2gb). National Zip boundaries are about 450mb without appended data.
