Function parse_timeout

impit-python/src/request.rs:18–34

Parse a Python `timeout` argument into `Option >`: - `USE_CLIENT_DEFAULT_SENTINEL` string (not provided / explicit sentinel) → `None` (inherit client default) - Python `None` → `Some(None)` (disable timeout) - Python `float` → `Some(Some(Duration))` (specific timeout)

(
    timeout: Option<Either<f64, &str>>,
)

/// - Python `None` → `Some(None)` (disable timeout)
/// - Python `float` → `Some(Some(Duration))` (specific timeout)
