serde support added

[constraintAutomaton]

I think it would be good to add support for serde this way to user can convert the bib library to other formats more easily (for example store the references into a mongo database or conversion into another reference system)

Thanks for your PR!

Could you make serde an optional feature? You'll just need to change your dependency declaration to

serde = { version = "1.0", optional = true }

and mark the derived traits like this:

#[cfg_attr(feature = "serde", derive(Serialize, Deserialize))]

Please test whether the crate compiles with and without the feature enabled.
