Changes from 2.10.5 to 2.11.0

• New AVX512 support for the bitshuffle filter. This is a backport of the upstream
  bitshuffle project (https://github.com/kiyo-masui/bitshuffle). Expect up to 20%
  better compression speed
  on AMD Zen4 architecture (7950X3D CPU).

• Add c-blosc2 package definition for Guix. Thanks to Ivan Vilata.

• Properly check calls to strtol. Fixes #558.

• Export the b2nd_copy_buffer function. This may be useful for other projects
  dealing with multidimensional arrays in memory. Thanks to Ivan Vilata.

• Better check that nthreads must be >= 1 and <= INT16_MAX. Fixes #559.

• Fix compile arguments for armv7l. Thanks to Ben Greiner.
