Is your feature request related to a problem? Please describe.

Currently, the encoding expects only 1 JSON log at the time. If the data sent to the extension consists of multiple JSON entries, it will fail:

Unmarshal: there are bytes left after unmarshal [...]

Describe the solution you'd like

I would like if the encoding extension could decode multiple JSON logs. This would be important for use cases where the logs are coming from Google cloud storage, in which each line is 1 JSON log. The logs should be grouped correctly by the resource attributes.
