volk-2.3.0-bp152.1.1

- Update to version 2.3.0
  * Better reproducible builds
  * CMake improvements
    + ORC is removed from the public interface where it was never
    supposed to be.
    + CMake fixes for better usability
  * Enforce C/C++ coding style via clang-format
  * Kernel fixes
    + Add puppet for `power_spectral_density` kernel
    + Treat the `mod_range` puppet as a puppet for correct use
    with `volk_profile`
    + Fix `index_max` kernels
    + Fix `rotator`. We hope that we finally found the root cause
    of the issue.
  * Kernel optimizations
    + Updated log10 calcs to use faster log2 approach
    + Optimize `complexmultiplyconjugate`
  * New kernels
    + accurate exp kernel is finally merged after years
    + Add 32f_s32f_add_32f kernel to perform vector + scalar float
    operation

- Update to version 2.2.1
  Changes
  * Fix loop bound in AVX rotator
  * Fix out-of-bounds read in AVX2 square dist kernel
  * Fix length checks in AVX2 index max kernels
  * includes: rearrange attributes to simplify macros Whitespace
  * kernels: fix usage in header comments
- Update to version 2.2.0
  Highlights
  * Dropped Python 2 build support
    + Removed Python six module dependency
  * Use C11 aligned_alloc whenever possible
  * Add VOLK version in volk_version.h (included in volk.h)
  * Improved CMake code
  * Improved code with lots of refactoring and performance tweaks

- Update to version 2.1.0
  * The AVX FMA rotator bug is fixed
  * VOLK offers `volk::vector<>` for C++ to follow RAII
  * Move towards modern dependencies
  - CMake 3.8
  - Prefer Python3
  - We will drop Python2 support in a future release!
  - Use C++17 `std::filesystem`
  - This enables VOLK to be built without Boost if
    available!
  * more stable CI
  * lots of bugfixes
  * more optimized kernels, especially more NEON versions

- First version of standalone VOLK package, version 2.0.0
