 Changes from python-blosc to python-blosc2
 ------------------------------------------
 
-* The functions `compress_ptr` and `decompress_ptr` are replaced by pack and unpack since Pickle protocol 5 comes with out-of-band data.
-* The function `pack_array` is equivalent to `pack`, which accepts any object with attributes `itemsize` and `size`.
-* On the other hand, the function `unpack` doesn't return a numpy array whereas the `unpack_array` builds that array.
-* The `blosc.NOSHUFFLE` is replaced by the `blosc2.NOFILTER`
-* A bytearray or NumPy object can be passed to the `blosc2.decompress` function to store the decompressed data.
