Write a function with the header void chacha20_block_sse(chacha20_ctx *ctx, uint32_t output[16]) that behaves exactly like the function chacha20_block but uses SSE instructions to accelerate the rounds. The file you submit should be named exactly hw2_chacha.c and should not include a main function. The chacha20_block function is shown below.

To be eligible for credit programs must report no warnings when compiled with gcc -std=c99 -W

Write a function with the header void chacha20_block_sse(chacha20_ctx *ctx, uint32_t output[16]) that
