Subject: [PATCH] Fixed inability to disable dziFormat

-d / --dziFormat was hardcoded to set dziFormat to true. dziFormat is already defaulted to true. Changed to -d takes boolean true/false.
In sliceImage "if [ ! dziFormat ] " was testing if the variable was unset on some shells. Changed to string comparison for greater portability.
