Node `Buffers` are subclasses of `Uint8Array` and we don't use any `Buffer`-specific functions, so do not demand `Buffer`s where `Uint8Array`s will do. `Buffer`s are still used in the tests because the `Buffer` requirement needs pull out of (at least) the `cids` and `multihash` modules first.

I'm afraid this is incorrect:
[...new Uint8Array([ new Uint8Array([1, 2, 3]), new Uint8Array([4, 5]) ])] // [0, 0]It's probably best to change line 184 to bufs.push(...chunk)

I've updated it to use Unit8Array.set instead.

📝 Probably this package needs major version bump because output is not backwards compatible.

If other modules in the stack actually requireBuffers, let the failure occur there.Buffers are still used in the tests because theBufferrequirementneeds pull out of (at least) the
