disarm64 definitions

This library provides structures and enums for describing AArch64 (ARMv8) instructions. The approach might seem to be closer to what the opcodes library (a part of GNU binutils) does, although the central motive is deserialization/parsing of a definition file - what TableGen (of LLVM) employs.

By default, the crate is built with std support. If you intend not to depend on the std crate, here is the syntax to use instead:

disarm64_defn = { version = "0.1", default_features = false }
