Feature Request: Write JSONDocument to GLB-formatted Uint8Array

[mattrossman]

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

I have a JSONDocument that I need to export as-is to GLB format.

Describe the solution you'd like

A function for writing JSONDocument directly to GLB format.

Describe alternatives you've considered

I could call readJson() to convert the JSONDocument to a Document and then call writeBinary() on that document. However, this forces the document to pass through glTF-Transform's resource graph which may modify its contents.

What I've had to do instead is copy/paste bits of the glTF I/O code from Three.js to write the GLB file, but would prefer to use glTF-Transform as my all in one glTF import/export solution.

Additional context

Seeing as there's a binaryToJSON() function for reading a GLB-formatted Uint8Array directly to JSONDocument, it seems reasonable to have a JSONToBinary() function for the inverse behavior (or whatever capitalization is preferred).

Just saw this is discussed in #746 and #1280 (was searching for "JSONDocument" before posting this), closing
