blosc2: updated to 2.15.1

Changes from 2.15.0 to 2.15.1

* Do not pass `-m` flags when compiling `shuffle.c`. This prevents the
  compiler from incidentally optimizing the code called independently
  of the runtime CPU check to these instruction sets, effectively
  causing `SIGILL` on other CPUs.

* Internal LZ4 sources bumped to 1.10.0.

* Allow direct loading of plugins by name, without relying on
  the presence of python. Thanks to @boxerab.

* Add `b2nd_nans` method
