0.12.0

Added

• numba-dppy is a standalone package now. Added setup.py and conda recipe.
• Offload diagnostics.
• Controllable fallback.
• Add flags to generate debug symbols.
• Implementation of np.linalg.eig, np.ndarray.sum, np.ndarray.max, np.ndarray.min, np.ndarray.mean.
• Two new re-write passes to convert NumPy calls into a pseudo numba_dppy call site to allow target-specific
  overload of NumPy functions. The rewrite passes is a temporary fix till Numba gains support for target-specific overlaods.
• Updated to dpCtl 0.5.* and dpNP 0.4.*

Changed

• The dpnp interface now uses Numba's @overload functionality as opposed to the previous @lower_builtin method.
• Rename DPPL to DPPY.
• Cleaned test code.
• DPPLTestCase replaced with unittest.TestCase.
• All tests and examples use with device_context.
• Config environment variables starts with NUMBA_DPPY_
  (i.e. NUMBA_DPPY_SAVE_IR_FILES and NUMBA_DPPY_SPIRV_VAL)
• Remove nested folder dppl in tests.
• No dependency on cffi.

Removed

• The old backup file.
