1.5.5 (Patch/Security Release) - hwb() ReDos patch (low-severity)

Release notes copied verbatim from the commit message, which can be found here: 0789e21284c33d89ebc4ab4ca6f759b9375ac9d3

Discovered by Yeting Li, c/o Colin Ife via Snyk.io.

A ReDos (Regular Expression Denial of Service) vulnerability was responsibly disclosed to me via email by Colin on Mar 5 2021 regarding an exponential time complexity for linearly increasing input lengths for hwb() color strings.

Strings reaching more than 5000 characters would see several milliseconds of processing time; strings reaching more than 50,000 characters began seeing 1500ms (1.5s) of processing time.

The cause was due to a the regular expression that parses hwb() strings - specifically, the hue value - where the integer portion of the hue value used a 0-or-more quantifier shortly thereafter followed by a 1-or-more quantifier.

This caused excessive backtracking and a cartesian scan, resulting in exponential time complexity given a linear increase in input length.

Thank you Yeting Li and Colin Ife for bringing this to my attention in a secure, responsible and professional manner.

A CVE will not be assigned for this vulnerability.
