Missing support for union data type

[Vithiyamuthukumar]

I have union data type field inside my C structure and YAML data for the same. I am unable to use libcyaml library in this case. LIBCYAML does not have corresponding CYAML_FIELD and CYAML_VALUE for union data type in C.

Unions are basically implemented on the tlsa/unions branch, but I need to write a load of tests for it.

@tlsa I see the branch hasn't been merged and it has been a year. I need it so how confident are you that it is okay to merge into my own repo?

Hello. Just a few words to say that this feature would be useful to me. I understand that writing tests is a huge amount of work, but it is too bad to have the feature up and running but not released.
