Result mode – line

[V0ldek]

Is your feature request related to a problem? Please describe.
The current implementation focuses on quickly returning locations of matches. The output is not human-readable though – we either get an aggregate of the number of hits or byte values. A first attempt at getting something that could be used as a simple CLI query tool (without focusing on massive datasets, or considering sparse results) would be to output the line number and the line at which a match is made.

Describe the solution you'd like
The implementation should be completely outside of the engine itself – we don't want it to influence the throughput of the main solution in any way. This is already achieved with the QueryResult trait.

As an example output, if I try to run the query $.a..c on the document:

{
    "a": {
        "b": {
            "c": [
                42,
                17,
                {
                    "c": "hello"
                }
            ],
    }
}

we expect to get an output resembling

4 |             "c": [
8 |                     "c": "hello"

Additional context
This obviously only makes sense for non-compressed JSON documents, but that's not something we can easily influence.
