... | Parses this BinaryString to Long.
<p>Note that, in this method we accumulate the result in negative format, and convert it to
positive format at the end, if this string is not started with '-'. This is because min value
is bigger than max value in digits, e.g. Long.MAX_VALUE is '9223372036854775807' and
Long.MIN_VALUE is '-9223372036854775808'.
