Feature Request: A field-attribute macro to link a struct field with a database name

[EvanCarroll]

Serde provides field attributes that allow me to link the field names of a struct to JSON for the purposes of serialization and serialization. I would love the ability to this SQLx too,

Desired syntax,

struct Foo {
    #[sqlx(rename(column = "id_node"))]
    id: u64,
}

This is done here #227
