Describe the bug
A wrong read error is given when a JSON string is terminated at a specific place. For example:

{"duck": 42.

Will give a YYJSON_READ_ERROR_INVALID_NUMBER. However, it should be YYJSON_READ_ERROR_UNEXPECTED_END.

Your environment

• OS: macOS Ventura 13.0
• Compiler: Apple clang 14

Additional context
I've implemented a streaming read in DuckDB using yyjson, and we read a file block-by-block. The block boundaries are arbitrary, so this happened while running a test.

I've changed occurrences of return_err(cur - 1, INVALID_NUMBER, msg); in yyjson.cpp to return_err(cur, INVALID_NUMBER, msg);, which seems to solve the problem.
