Move deserialize_u32/64_le and serialize_u32/64_le implementations from serialize.c to serialize.h as static inline functions. These tiny helpers benefit from inlining to avoid function call overhead on hot paths during block sync. Co-authored-by: JesterHodl <jesterhodl@jesterhodl.com>

Thanks for this contribution! The UB fix and consolidation are exactly right. We added one small refinement on top: making the helpers Appreciate you catching the UBSan issue and taking the initiative to clean up the duplication! |

This attempts to fix #30 by: - consolidating `read_u32_le()`, `read_u64_le()`, `write_u32_le()`, `write_u64_le()` - renames them to `deserialize`/`serialize` to avoid conflicts with `protocol/serialize.c` functions with the same name, but different type and signature - removes UBSan bug from `deserialize_header()` by using `deserialize_u32_le()` --------- Co-authored-by: Seth Atwood <sethmerrick@gmail.com>
