CRUSH 2.42-1 release

The release fixes the previously broken Linux packages (.rpm and .deb) and adds support for SOFIA/HIRMES simulated (v.6) data in all operating modes. The wrapper script (bash) has also been updated for forward compatibility with Java 10+ by removing deprecated runtime options. The release also provides fully populated and Rev. G compliant headers for SOFIA instruments (HAWC+ and HIRMES). Many updates to the bundled and online documentation. And, of course there are many smaller fixes and improvements all around.
