Summary
Multiple soundness issues
Details

RUSTSEC-2024-0377 contains multiple soundness issues:

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