hexdump processes a vector as a contiguous sequence of bytes, regardless of V's value type, so hexdump should get a pointer and use uint8_t to read the data. Some vector types have a lock and some atomics in their operator[], so let's avoid hammering those. Signed-off-by: Zygo Blaxell <bees@furryterror.org>
