v0.8.3

• Add bool flag typedef_enum_with_defmod (default false)
  • This flag's behaviour is intended to be the default behaviour. Its release
    starts a transition period for users to begin enabling this flag.
  • This flag causes typedef enumeration/identity names to be prefixed with
    its defining module name, per docs/design.md, instead of the current
    behaviour of using the residing module.
  • Using this flag also fixes a related bug. Namely, if a collision of a
    typedef name occurred, behaviour with flag set to false silently ignores
    this fact, and uses one of the enums in place of all conflicting enums.
    Turning on this flag would now cause a code generation error to be
    raised when this conflict occurs.
  • where an enumeration is defined within a typedef that contains a union,
    the enumerated language type that is generated is named according to the name
    of the typedef with _Enum appended to the name. This improves upon the
    present behaviour (which duplicates the definition for every place of usage) by
    giving a name to such enumerations, thus de-duping them.
  • Enabling this flag also partially fixes #245, including the sid-id case in the
    real OpenConfig schema.
• Add DefiningType Helper to util package.
