@rexagod This LGTM but it looks like this needs to be rebased against master to resolve merge conflicts.

} else {
reading = false;
const res = await value;
if (res == null) throw new ERR_STREAM_NULL_VALUES();

I'm not sure I agree with this throwing. There is no way to catch this? I think it should do readable.destroy(new ERR_STREAM_NULL_VALUES()). @lpinca Thoughts?

I would like @lpinca's feedback here on whether we throw err or destroy(err).

@rexagod Looks like a merge commit somehow got in here, can you rebase this against master?

Throws `ERR_STREAM_NULL_VALUES` error if a null value is passed to
`Readable.from`. Also added docs for the same.
