Constant encoding_rs::ascii::ALU_STRIDE_SIZE

pub const ALU_STRIDE_SIZE: usize = 16;

Safety invariant: this is the amount of bytes consumed by unpack_alu. This will be twice the pointer width, as it consumes two usizes. This is also the number of bytes produced by pack_alu. This is also the number of u16 code units produced/consumed by unpack_alu/pack_alu respectively.
