Stream in geojson/geobuf and stream out tiles

Hi! Having some trouble setting up tippecanoe to do tiling without actually writing to file and I would love some assistance.

I was able to get geojson to stream with the following command:

`echo '{"type":"Polygon","coordinates":[[[0,0],[0,1],[1,1],[1,0],[0,0]]]}' | tippecanoe -L'{"file":"", "layer":"test", "description":"test"}' -e test`

Which didn't feel quite right, as I am basically passing in an almost empty layer json just to get it to stream. What is the intended method to accomplish this with geojson? Related to that, how would I pipe in a geobuf with the same method? When I try inserting an example base64 encoded geobuf, e.g. `CgRuYW1lGAAiHQobCgwIBBoIAAAAAgIAAAFqBwoFdGVzdDFyAgAA` into stdin then I get an error about an unexpected character, leading me to believe that it is expecting geojson. Would love some guidance on this.

I also am wondering if it is possible to stream the output to stdout in some sort of structured way instead of writing to files/.mbtiles. From the documentation it looks like this may be a lot more complicated/not feasible for me to write, but if there are any known methods to do this that would be most appreciated.

Thanks!

Start by reproducing the documented tippecanoe command for streaming GeoJSON and the base64 geobuf example through stdin. The issue also asks about structured stdout output instead of files or MBTiles; completion would require a clearly documented and supported approach for both input formats and output streaming.
