stdin segment fails on additional/no line breaks in json

[Mynacol]

I modified a json export with another tool (jq) and was unable to read it back into flowpipeline.
In the first attempt, jq pretty-printed the json with newlines between each json field (not a full flowpipeline object), which lead to a failure decoding the json.
In the second attempt I instructed jq to "uglify" the json, which removes all newlines. But then the import fails because the file contains one very long line, leading to a "buffer too big" error.

Both errors are caused by the input segment using a scanner and always processing the data line-by-line. This however is only successful for a subset of valid json files.
