Avoid doing unnecessary allocations,
don't use `String.operator[]` to access single characters,
or creating substrings that are not needed.
Reuse the date-parser for cookie dates, instead of having two
separate parsers. The cookie-date-parser was very forgiving,
and only tested very little.
It's unlikely that there will be wildly different cookie formats
in actual use, when the specification only allows for one format.
