ruma-serde

This crate contains (de)serialization helpers for other ruma crates.

Part of that is a fork of serde_urlencoded, with support for sequences in Deserialize / Serialize structs (e.g. Vec<Something>) that are (de)serialized as field=val1&field=val2 (instead of the more common field[]=val1&field[]=val2 format supported by other crates like serde_qs).
