Validation

• [ ] The bug also occurs if the latest version from the develop branch is used.
• [X] I can successfully compile and run the unit tests.

[nlohmann]

There is an error and index 0 which means already the first byte is invalid. The spec (https://bsonspec.org/spec.html) does not allow byte 0xB6 as first byte.

When I look at your file, the first byte is 0x6E, however. Can you please double check your example?

@nlohmann I don't know how to modify it. Can you teach me?
