CLI: read standart input

[yshalenyk]

It might be nice to have ability to read stdin to work with remote files.
For example something like
wget -O - <url> | spoonbill
or
wget -O - <url> | spoonbill -

Or maybe concatenate multiple jsonl files
cat jsonl1 jsonl2 | spoonbill

Hmm, wouldn't the data need to be stored temporarily, since it needs to be read twice (once for analysis, and again for flattening/writing)?

[yshalenyk]

Yes indeed! But I think it might be possible to implement this feature at some degree if #132 implemented.
Anyway, its issue is more discussion than a enhancement.

[jpmckinney]

I think there is not enough demand for this feature.
