Thank you for the PR and detailed Unit test.

There's no need for the double conversion, @barspi suggest a simpler solution, just

return (length * lengthAdjusted) / interpreter.getPackedLength(lengthAdjusted);

While you are at it, it would be great to also change the following method:

 private int getUninterpretLength(int length, Interpreter interpreter) {
        if (length > 0) {
            int lengthAdjusted = length + length % 2;
            return (length * lengthAdjusted) / interpreter.getPackedLength(lengthAdjusted);
        }
        return 0;
    }

(the one that uses an Interpreter instead of a BinaryInterpreter.
