key_bytes is calculated incorrectly

[DominaeDev]

AES/AES.hpp

Line 89 in a415713

static constexpr size_t key_bytes = key_bits / sizeof(char);

Should be:
static constexpr size_t key_bytes = key_bits / 8;
Because a byte is always 8 bits and sizeof(char) is 1.

Good catch, If you want to open a tiny PR for that line I’ll happily accept it, otherwise I’ll take care of it when I get a chance.
