py-bcolz: updated to 1.2.1

Changes from 1.2.0 to 1.2.1:
C-Blosc internal sources updated to 1.14.3. This basically means that internal \ 
Zstd sources are bumped to 1.3.4, which may lead to noticeable improved speeds \ 
(specially for low compression ratios).
np.datetime64 and other scalar objects that have __getitem__() are now supported \ 
in _eval_blocks().
Vendored cpuinfo.py updated to 4.0.0 (ARM aarch64 is recognized now).
Allow setup.py to work even if not on Intel or ARM or PPC archs are found.
