Convert aes_siv_cmac_test to v1 format (#159)

This is v0 coverage to augment existing coverage. Unlike the
aead_test_schema_v1 schema, and aead_aes_siv_cmac_test.json vectors
the aes_siv_cmac_test.json vectors do not provide separated iv/tag data.

The daead_test_schema is almost identical to the aead_test_schema but
omits ivSize/tagSize in test group, and iv/tag in test vectors. To
convert the v0 schema to v1 we only need to adjust the notes ref'd by
the flags to the structured v1 format.

The EdgeCaseSiv flag is described equivalently as in
aead_aes_siv_cmac_test.json
