Check for remaining array items, a pending value header or an unfinished container when an async decoding stream ends. Throw RangeError instead of reporting successful completion with missing records.

For example, a stream containing [{ id: 1 }, { id: 2 }] with its last byte missing currently finishes and returns only { id: 1 }. With this change, it still yields the complete first item, then rejects when it detects that the second item is incomplete. Complete streams retain their current behavior.

Adds regressions for array streams missing a whole item or part of its value, plus multi-record streams ending inside a string or nested object.

Closes #299
