[feature request] Automatic chunking of data files by file_packager and FS (and potentially wasm files as well?)

It would be nice if file_packager / FS supported configurable chunking of produced data files. This would be beneficial for browser caching and for dealing with compressed files >2Gb (all individual files are < 2Gb).

This is currently possible by manual chunking of directories, which is already not bad, but would be better if this was automatic / configurable, or at least if there was some recipe for this in docs.

TensorFlow.js does it (at least couple years ago) for distribution of the models
