Dereferencing an unaligned pointer is UB and leads to unaligned SSE read crashes

[0vercl0k]

We have no guarantee that the threads context are stored at an aligned offsets in the dmp file, as a result those are UBs:

2. https://github.com/0vercl0k/udmp-parser-rs/blob/main/src/udmp_parser.rs#L658

I've seen this leads to crashes in an application using udmp-parser-rs when the compiler reads from the context using SSEs instructions:
