1. How to convert a string to integer with SIMD acceleration (explained with NEON intrinsics)
// vld1q_u8 to load 16 chars
// create masks:
//   is_digit (0-9) using vceq_u8
//   is_plus  --> vaddvq_u8 --> to get quick answer --> update global state
//   is_minus --> vaddvq_u8 --> to get quick answer --> update global state
//   is_space
//   ignore_mask = vorrq_u8 --> combine masks (is_plus/minus/space)
// convert to digits --> subtrack '0', vsubq_u8/vdupq_u8
// apply digit mask and convert them to 0, vbslq_u8
