Generates IO methods (pack, unpack) from structure definitions. Also defines packed_sizeof to give the on-disk size of a packed structure, which is smaller than sizeof would give, if the struct is marked as align_packed.
julia> using StructIO

julia> seekstart(buf); unpack(buf, TwoUInt64s) # Default endianness depends on machine
TwoUInt64s(0x0807060504030201, 0x100f0e0d0c0b0a09)
julia> seekstart(buf); unpack(buf, TwoUInt64s, :BigEndian)
