Contributions summary:Matt focused on improving the handling of unicode surrogate pairs within the BSON decoder. This primarily involved enhancing the `json_scanner.go` file by correctly unmarshalling and handling these pairs in the `UnmarshalExtJSON` function. Furthermore, they added various tests within `unmarshal_test.go` and `json_scanner_test.go` to ensure the correct parsing of these characters across different scenarios. This work aimed to improve the stability and correctness of BSON parsing for a wider range of unicode strings.
