Mozilla Bug: 1884879
Differential Revision: https://phabricator.services.mozilla.com/D207796

If a long string of hex digits are passed to unicode-range, the code tries to
parse them into a number before checking whether there are more than the 6 digits
allowed by the syntax, and this may lead to integer overflow.

To avoid this, check the number of digits and error out earlier if there are
too many to possibly be valid.

This prevents needing cssparser changes every time we add one, and makes
them configurable at runtime.
