Implement consistent randomized fingerprint (#20)

Browse source 
- Uses a chacha20-based CSPRNG to generate randomized fingeprints
 - Refactors generation of randomized fingerprints, removing many redundant shuffle functions.
 - Adds Seed field to ClientHelloID
 - ClientHelloID.Version is now a string (was uint16)
