Changes from 1.14.3 to 1.14.4

• Added a new DEACTIVATE_SSE2 option for cmake that is useful for disabling
  SSE2 when doing cross-compilation (see #236).

• New check for detecting output buffers smaller than BLOSC_MAX_OVERHEAD.
  Fixes #234.

• The complib and version parameters for blosc_get_complib_info() can be
  safely set to NULL now. This allows to call this function even if the user is
  not interested in these parameters (so no need to reserve memory for them).
  Fixes #228.

• In some situations that a supposedly blosc chunk is passed to
  blosc_decompress(), one might end with an Arithmetic exception. This
  is probably due to the chunk not being an actual blosc chunk, and divisions
  by zero might occur. A protection has been added for this. See #237.
