v1.6.4

• Fix improper use of sync/atomic on 32 bit systems causing panics #154
  • Thanks @andersfylling for reporting this issue.
• Improve godoc and fix code style (#149, #150, #151)
  • Thanks @cristaloleg
• Allows concurrent use of SetReadLimit in respect to the Read goroutine #154
  • Reasoning behind this change is that if you are handling messages async to the read goroutine, you might
    want to adjust the read limit in those instead co-ordinating explicitly with the read goroutine.
