Converting only select message members

[authaldo]

Hey,

first of all thanks for this useful library!

In our use-case we discovered the caveat that converting rather large messages into their corresponding YAML format can take a considerable amount of time. Since we've been only interested in a few selected members of the messages (mainly 'header' information describing the detailed structure of large data blocks), we added a small utility function for converting those message members into their corresponding YAML-format.

I'm not a maintainer, but this sounds like a useful feature. It would probably be good if you could add some tests for it, and sign-off your commit(s) (git commit --amend -s).

Done, unfortunately I am not even able to request a review from someone. I am not sure whether this repository is still maintained, given the fact that your two pull requests are open for over a year now and didn't receive any kind of response.

Thanks for adding the test!

Yeah, I think this repository was more of an experiment/proof-of-concept. I'll ask around.
