Update serde to 1.0 and strason to 0.4
The `serde_struct_impl!` macro has been modified to be compatible with the serde 1.0 crate, we use this macro and not the `serde_derive` crate because the latter doesn't support Rust 1.14.0 which is shipped on Debian stable and we should remain compatible with it. Two new features were added: - "serde": enables serialization/deserialization for common types, it pulls the serde 1.0 dependency. - "serde-decimal": enables serialization/deserialization for `UDecimal`/`Decimal`, this pulls the strason 0.4 depdendency and the serde 1.0 dependency.
