mudp: fix unaligned 32-bit read when parsing peer ID
The code previously read a 32-bit value from a uint8_t
buffer using a direct cast and dereference.
This can cause unaligned memory access and undefined
behavior on architectures that do not support unaligned
reads, potentially leading to a one-packet crash.
Fix this by reading the bytes individually and
combining them manually.
