Description

RUSTSEC-2024-0377 contains multiple soundness issues:

Bytes::read() allows creating instances of types with invalid bit patterns
BytesIter::read() advances iterators out of bounds
The BytesIter trait has safety invariants but is public and not marked unsafe
write_float() calls MaybeUninit::assume_init() on uninitialized data, which is is not allowed by the Rust abstract machine
radix() calls MaybeUninit::assume_init() on uninitialized data, which is is not allowed by the Rust abstract machine

Version 1.0 fixes these issues, removes the vast majority of unsafe code, and also fixes some correctness issues.
