2.4.1

2.4.1

• Fixed Result.Decode and Result.DecodePath after Reader.Close so stale
  results return closed-database errors instead of reading invalidated data.
• Fixed Networks and NetworksWithin with SkipEmptyValues so malformed
  pointer cycles return an error instead of looping indefinitely.
• Fixed top-level Decode validation so nil and non-pointer values are rejected
  consistently before custom Unmarshaler dispatch.
• Fixed ReadMap and ReadSlice iterator cleanup so callers that stop
  iteration early can continue decoding from the correct next value.
• Fixed an oversized data-pointer bounds check so malformed databases return an
  offset error instead of risking a panic on 32-bit builds.
• Fixed migration and README examples to reference the public mmdbdata.Decoder
  type for custom unmarshaling.
