Do not work with valgrind 3.21

[Fi3]

I'm using fedora 38 and when I install valgrind i get the 3.21 version. Iai seem to not work with it, if I run the example in the README I get:

thread 'main' panicked at 'no entry found for key', /home/user/.cargo/registry/src/github.com-1ecc6299db9ec823/iai-0.1.1/src/lib.rs:163:40

If I print events at line 160 of lib.rs I get: Events: {"Ir": 442824}

Downgrading to valgrind 3.18 solve the issue
