Merge branch 'hotfix-81-oaisim-2' into 'develop'

Browse Source 
Hotfix 81 oaisim 2

this branch fixes a few issues mainly with the oaisim testcases 
 - improved gain control for oaisim
 - updated testcase list options for oaisim
 - XFORMS now command line options for oaisim and unitary sims
 - build script improvements for sudo; HW=None and XFORMS=1 now default
 - fixed SNR calculation in abstraction mode

See merge request !15
