blosc2: updated to 2.13.0

Changes from 2.12.0 to 2.13.0

* Added a new BLOSC_FILTER_INT_TRUNC filter for truncating integers to a
  given number of bits.  This is useful for compressing integers that are
  not using all the bits of the type.

* Optimized zstd, specially when using dicts.

* Initialize grok library when loading the plugin. This is needed for other plugins
  to be able to use it without the need of importing the package.
