Use new b2nd_deserialize_meta_inline() in forthcoming c-blosc2 3.1.0

[FrancescAlted]

This will allow to compile this plugin without the need to link with libblosc2 at all. But we will need to wait until a new C-Blosc2 release would be out. Addresses #22.

Hi,

Testing this PR with hdf5plugin tests from silx-kit/hdf5plugin#388, I encountered the following 2 issues:

• Use of BLOSC2_MAX_DIM:

  -    int64_t shape[BLOSC2_MAX_DIM];
  -    int32_t chunkshape[BLOSC2_MAX_DIM];
  -    int32_t blockshape[BLOSC2_MAX_DIM];
  +    int64_t shape[B2ND_MAX_DIM];
  +    int32_t chunkshape[B2ND_MAX_DIM];
  +    int32_t blockshape[B2ND_MAX_DIM];

• Linking error for error messages:

  OSError: /home/tvincent/miniforge3/envs/py314/lib/python3.14/site-packages/blosc2_grok/libblosc2_grok.so: undefined symbol: blosc2_error_string
  

  Removing BLOSC_ERROR macros from blosc2_grok fixes the issue. Having BLOSC_ERROR relying on header only definitions is maybe a better fix.

Good remarks. Both fixed in 41ef2b9.

Merged, as c-blosc2 3.1.0 is out for a while now.
