SAX-like parsing and writing

[xelatihy]

Is your feature request related to a problem? Please describe.
The library requires loading into its own data structure when reading and building a data structure when writing.
This incurs some overhead if one wants to just load or save a custom data structure.

Describe the solution you'd like
It would be good to have a direct interface to the low-level parser, maybe in terms of callbacks for reading. For writing, just exposing a simple API to format the various JSON elements might be good.

Describe alternatives you've considered
Right now, one parses the data into the yyjson document and then reads from it.

I do have plans to add a streaming or SAX API, maybe in version 0.5 or 0.6.

@ibireme hey, how is the streaming API coming along? That's the feature we're waiting for to start using this library!

What is the progress of supporting SAX api? @ibireme

Does the latest released version support it?

No progress yet, I've tried to design some APIs but they seem hard to use.
