eserde: Reporting Multiple Deserialization Errors at Once

The serde library aborts deserialization upon encountering the first error, which is inconvenient when dealing with user-provided JSON payloads (e.g., a REST API request body). eserde solves this by reporting all deserialization errors at once, significantly improving the developer experience. By replacing `#[derive(serde::Deserialize)]` with `#[derive(eserde::Deserialize)]` and using eserde's deserialization functions, developers can easily obtain all error messages, reducing the number of API interactions. eserde currently supports JSON and plans to support YAML and TOML in the future.
