Fiona: Support GeoJSONSeq

[dazza-codes]

https://gdal.org/drv_geojsonseq.html says a GeoJSONSeq file is:

• Plain text file with GeoJSON data - identified from the file extension .geojsonl or .geojsons

versions

$ pip freeze | grep -i fiona
Fiona==1.8.4
$ pip freeze | grep -i gdal
GDAL==2.4.0

format support

$ ogrinfo --formats | grep -i json
  GeoJSON -vector- (rw+v): GeoJSON
  GeoJSONSeq -vector- (rw+v): GeoJSON Sequence
  ESRIJSON -vector- (rov): ESRIJSON
  TopoJSON -vector- (rov): TopoJSON

BTW, add a similar --formats option to fio for a bonus 💯 points!

Yes, thanks for the reminder. GeoJSON text sequences were pretty much born in this project and a lot of the API is already compatible, but I've overlooked adding the format to the list.

BTW, is there a glossary for the acronyms of the supported drivers?

I was just going to comment that the "ESRIJSON" driver is missing as well (it is in the ogrinfo list above); @sgillies if you add that one as well when you update the format list I'd be much obliged!
