Binary tools

Work in progress not ready to any practical use

Goals:

• Efficient binary serialization
• Pack/unpack byte tools
• 2 flavors of space-effecient varint packing
• CRCs and CRC-protected blocks
• Async variants

Some publics

SmartInt codec

Variable-length signed and unsigned integer codec, see [src:Smartint]. For not too small numbers it is slightly more effective than VarInt codec, for example on Long values it saves a byte.
