Json daccor

json daccor is a json-schema validation library that accepts json-c
objects as input, and seems to be designed for openwrt, a system
with very similar requirements to BMCs.

Using this library has several motivations.  First, it keeps
libcper as a C application so integrations aren't required to provide
a c++ toolchain to be able to run unit tests.
Next, it means that we avoid an "expensive" conversion in unit tests
from json-c -> nlohmann just so we can use a third library, valijson
In terms of dependency count, it drops one dependency.
(nlohmann+valijson) to (json daccor)
Finally, it means that in the future versions of the library, we
can allow json-schema verification as an option in the library
itself, which would allow us to give a CLI option for verifying
schema on any arbitrary output (helping in debugging).

Testing to see if it will work and what improvements it makes
