New built-in types

[extremeheat]

These will reduce the need to resort to coding custom types:

loop - (Array) Keep reading the specified container until end of buffer
loopNT - (Array) Keep reading the specified container until 0x00 (null term)
encapsulated - (Struct) Embedded binary data structure with a length prefix
encapsulatedNT - (Struct) Binary data structure, terminated with 0x00 (null-term) char
restBuffer - (Buffer) Read everything until EOF as a buffer
zigzag32/zigzag64 - (Int) ZigZag encoded VarInts
bitflags - (Struct) Packed booleans in integer
