Version 3.0.0
Changes:
* Do not use `lseek` nor `read` on SHM objects as they aren't
supported by POSIX and break on macOS.
* On some systems (macOS, Linux/ARM) shared memory objects are
allocated as multiples of the page size. Force the location of
meta-data structure.
* Add the name of the SharedArray to the numpy base object to make
it easier to track and delete them.
* Remove the msync/mlock/munlock module functions. Use the numpy
base object methods of the same name instead.
* Update the README.md file.
* Move to setuptools instead of distutils.
