pub fn extract_map_entry_raw(blob: &[u8], key: &str) -> Option<Vec<u8>>Expand description

This is useful for extracting a single property from overflow JSON without paying the cost of decoding all other properties.
Returns None if:
- The blob is not a TAG_MAP
- The key doesn’t exist in the map
- Deserialization fails
