GHSA-g753-ghr7-q33w: cyfs-base vulnerable to misaligned pointer dereference in `ChunkId::new`

The function ChunkId::new creates a misaligned pointer by casting mutable pointer of u8 slice which has alignment 1 to the mutable pointer of u32 which has alignment 4, and dereference the misaligned pointer leading UB, which should not be allowed in safe function.

Root Cause Analysis

The vulnerability is clearly located in ChunkId::new as shown in multiple sources:

The advisory specifically names this function
The GitHub issue #275 shows the vulnerable code pattern
The unsafe pointer cast and dereference operation matches the described UB
The file path matches the commit diff showing the test case addition
The operation violates Rust's safety requirements by performing unaligned accesses in safe code
