cryptsetup custom options

[Former user]

Is it possible to pass custom options to cryptsetup such as a detatched header, etc.? From reading the code it seems that adding a cryptsetup_args="" option under "process_commandline_options()" and replacing "cryptsetup_args=" in line 324 with a variable tied to that process_commandline_option in the "better-initramfs/sourceroot/functions.sh" file would accomplish this but I am currently unable to test it. I could submit an untested pull request if that would better represent what I mean.
