What's Changed

• fix bad hint (minor perf issue) by @lemire in #2610

Gotchas

If you run your code with development checks (in debug mode, or by setting #define SIMDJSON_DEVELOPMENT_CHECKS 1 prior to including the simdjson header), then the 4.3 series has additional checks for unsafe coding practices with respect to iterators. It is therefore possible that code that appeared to work with 4.2 or earlier might not work anymore. Refer to our documentation for the safe use of iterators.
