feature req:create checksums

multipar is a very useful tool, it is especially nice that it sequentially can create and check pars automatically in a queue. it would be fantastic if multipar could create/check sha256 or other checksums in a queue also. i am pretty sure i could just create .par files with zero block and zero redundancy which would also have the same effect, but it would be a lot nicer if there was an option on the create screen for "create checksum only" and it would create the user set default checksum for files or folders. there are not very many checksum creators out there and most are very basic i create about 30 tb of par files every year or more, but i also create about checksums for about 100 tb of files that only need a checksum.
