Closed issues 8, 7 and 5.
Extended `mkl.cbwr_set` to recognize `'avx512_e1'`, `'avx512_mic_e1'`, as as strict conditional numerical reproducibility, supported via `'avx2,strict'`, `'avx512,strict'` (see [issue/8](http://github.com/IntelPython/mkl-service/issues/8)).
Extended `mkl.cbwrt_get()` to mean `mkl.cbwr('all')`.
