/*
  Set-Cookie header field-values are sometimes comma joined in one string. This splits them without choking on commas
  that are within a single set-cookie field-value, such as in the Expires portion.

  This is uncommon, but explicitly allowed - see https://tools.ietf.org/html/rfc2616#section-4.2
  Node.js does this for every header *except* set-cookie - see https://github.com/nodejs/node/blob/d5e363b77ebaf1caf67cd7528224b651c86815c1/lib/_http_incoming.js#L128
  React Native's fetch does this for *every* header, including set-cookie.
