## Added

- Better error handling for geo data

## Changed

- Copy, don't stream, in-memory io.Readers like bytes.Buffer, bytes.Reader and strings.Reader
- Fix a bug where a panic under Go (but not TinyGo) would result in handlers returning 200 OK instead of 500 Internal Server Error by not deferring Close() on the response writer internally.
