Add serde annotations for configuration

[byhemechi]

The title pretty much explains it all, I'd love if it were possible to deserialise configuration with serde so that it can be exposed directly to things like WebAssembly

I'm happy to do this myself, I am just throwing this issue here before i get into it in case there are reasons to not do it/do it in a specific way

:)

Hi!
Yeah, seems like a good idea. I don’t see why not.
(Assuming that serde remains an optional feature?)

alright, i'll get into it.

(Assuming that serde remains an optional feature?)
