v0.8.2

SIMDe 0.8.2

Summary

• Start of RISCV64 optimized implementation using the RVV1.0 vector extension! Thank you @eric900115 @howjmay @zengdage
• 62 of the ARM Neon intrinsics added in SIMDe 0.8.0 had to be removed for not exactly matching the specs and real hardware
  (from the FCVTZS/FCVTMS/FCVTPS/FCVTNS families). This brings us down from 100% coverage of the NEON functions to 99.07%.

Implementation of Arm intrinsics

NEON
