@martin-g darling is exactly what I was thinking there should be when I was
making it! Refactored it a bit to break it up into NamedTypes and their schema
options , and fields and their schema options! So we get docs on fields and
types out of the box and super easily. Check it out:
```
#[derive(Debug, Serialize, Deserialize, AvroSchema, Clone, PartialEq)]
#[avro(namespace = "com.testing.namespace", doc = "A Documented Record")]
struct TestBasicWithAttributes {
#[avro(doc = "Documented Field")]
a: i32,
b: String,
}
```
Also I was able to solve the `doc` issue where ToTokens on Option was
flattening away None by manually preserving it in the output tokens:
```
fn preserve_optional(op: Option<impl quote::ToTokens>) -> TokenStream {
match op {
Some(tt) => quote! {Some(#tt.to_owned())},
None => quote! {None},
}
}
```
