Derive macro for implementing `TryFrom/TryInto` for `BoltType`

[elimirks]

Since cypher core types are isomorphic to JSON, it should be doable to implement something like #[derive(Serialize, Deserialize)] for BoltType.

The core types have pretty obvious translations.

ByteArray:

• Bytes or
• [u8] or
• Vec<u8>

int:

• i64 or
• i32 or
• u32
• etc etc

(notable, maybe no u64 for int since the JVM doesn't support u64, so I assume Neo4j doesn't either)

Spatial and graph types have less obvious translations into Rust, and maybe we could have a "sub-derive" similar to #[serde(serialize_with = ...)]. Temporal types can like likely map to std::time or an optional chrono dependency.

I'm writing this here because it's something my team talked about implementing internally, but thought it would make since to contribute to the OSS project. It's not super high priority for us but we want to eventually implement it.

Let me know if this makes more sense as a separate crate

Also interested in this, as chrono datetime objects are currently being serialized as strings with our current method of converting arbitrary structs into query parameters. Would like a way to automatically use Into rather than round tripping through serde if possible.
