devel/blosc: Update to 1.14.2

Notable changes since 1.12.1:
- Serious optimization of memory copy functions (see new
  blosc/fastcopy.c). This benefits the speed of all the codecs, but
  specially the BloscLZ one.
- As a result of the above, the BloscLZ codec received a new
  adjustment of knobs so that you should expect better compression
  ratios with it too.
- Fixed a buffer overrun that happens when compressing small buffers
  and len(destination_buffer) < (len(source_buffer) +
  BLOSC_MAX_OVERHEAD).
- New split mode that favors forward compatibility. That means that,
  from now on, all the buffers created starting with blosc 1.14.0 will
  be forward compatible with any previous versions of the library --at
  least until 1.3.0, when support for multi-codec was introduced.
