GHSA-2326-pfpj-vx3h lexical-core has multiple soundness issues

• crates.io lexical-core: < 1.0.0 → fixed in 1.0.0

`RUSTSEC-2024-0377` contains multiple soundness issues: 1. Bytes::read() allows creating instances of types with invalid bit patterns 1. BytesIter::read() advances iterators out of bounds 1. The `BytesIter` trait has safety invariants but is public and not marked `unsafe` 1. `write_float()` calls `MaybeUninit::assume_init()` on uninitialized data, which is is not allowed by the Rust abstract machine 1. `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.
