Add support for json lines

[cactusdualcore]

In accordance with SemVer, I bumped the minor version. Not too sure whether this I wanted though.

I was thinking about adding hjson support as well. If that is desired, I could implement it too. If possibly, I would include it in this PR before merging so as to only bump the version to 0.12?

I don't see the benefit of json lines over a "normal" json file containing an array. Do you have a use case that does not work with normal json?

It's two parts preference, one part convenience. There are technical reasons why one would prefer jsonlines over standard json, most importantly improved streamability, i.e. it's trivial to incrementally read and write the jsonlines format.

Ideally, I would have implemented something like

asset_server.load("all_the_assets.jsonl#1"); // loads the asset in the jsonlines file

This would allow short circuiting the asset loader for large files. I don't know enough about Bevy asset loaders to implement this well.

Besides streaming I can't think of any technical advantages of jsonlines though. Either way, it's effortless to convert a json array to jsonlines and back. Just add/remove brackets and commas.
