Summary:
This allows us to remove the Python binding without breaking existing zstd
users (commitcloud bundles). It might also make the future Rust migration
easier.
Using `zstd` create for its streaming APIs. `zstdelta`'s APIs cannot be used
since it requires decompressed length to be known, which wouldn't work for
streaming compressed data.
Note: For easier implementation, the Python land no longer processes data
in a streaming way. This is probably fine for the current bundle use-case.
In the long term, we might want to revisit the bundle format entirely.
As we're here, also expose zstdelta's APIs and add a test for it.
