Added functionality for MacOS X (#242)

* Added functionality for MacOS X

 Functionality for MacOS, updated module list in srw_common

* Update build_macos_gnu.env

* Update srw_common

* Update build_macos_gnu.env

The env/build_mac_gnu.env does not load srw_common module, but instead loads individual HPC-stack modules built locally on the Mac that contain higher-versions of some packages. This avoids conflicts with SRW builds for other platforms.

* Update srw_common

corrected the version of the gftl-shared

* Update build_macos_gnu.env

No need to load libpng module found in srw_common, as this is not being built as a part of the hpc-stack on MacOS X, rather installed system-wide.
