* whitespace
* clean up
* support message flags visible to SMP server to control notifications (and for any future extensions)
* simplify message flags encoding
* GET command
* groups agent protocol
* groups to chat protocol
* update groups doc / diagram
* group protocol commands

* another version of group protocol based on "broadcast" and "introduction" concepts
* update number of messages needed to establish connection
* corrections to broadcast and introduction protocols
* corrections in groups protocol
* corrections
* sign and verify agent messages with key sent in HELLO (TODO: hardcoded block size - should use size from handshake; verify signature of HELLO message itself; possibly, different MSG status if signature was not verified (currently ignored) or failed to verify (currently fails with AGENT A_ENCRYPTION - alternatively, change it to AGENT A_SIGNATURE))
* remove hardcoded block size, make it 4096 bytes
* verify signature of HELLO message before it is added to RcvQueue
* refactor
* update doc
* rename functions
* transport encryption (WIP - using fixed key, parsing/serialization works, SMP tests fail)
* transport encryption
* transport encryption: separate keys to receive and to send, counter-based IVs
* docs: update transport encryption and handshake
* transport encryption handshake (TODO: validate key hash, welcome block, move keys to system environment)
* change KeyHash type to newtype of Digest SHA256
* transport encryption: validate public key hash
* send and receive welcome block with SMP version
* refactor: parsing SMPServer
* remove unused function
* verify that client version is compatible with server version (major version is not smaller)
* update (fix) SMP server tests
* clrify encryption schemes
* increase SMP ping delay
* include authTag and msg size in encrypted message header, pad messages to fixed size
* use newtype for Key and IV bytestrings
* rename CryptoError constructors
* refactor Word to Int conversion
* refactor padding, replace padding character
* rfc corrections, comment
* rename aesTagSize -> authTagSize
* failing test
