Dustin Oprea d06a3c8963 ifd_builder: Implemented NewBuilderTagFromConfig() BT factory for testing. 
- Updated IfdByteEncoder tests to use it instead of hacking-together
  their own BT's (makes for more standardized, consistent testing).

- Universally refactored all core IFD knowledge implemented upon a
  single IFD name to instead work with IfdIdentity instances, instead,
  in order to validate that we only recognize the IFDs only in the
  context of the correct parents in the hierarchy.

- Implemented standard testing byte-order (assigned to
  TestDefaultByteOrder).
 2018-04-27 03:42:59 -04:00
