mf2sqn does not work in Docker container

[Adamtaranto]

MFannot throws an error when run with the --sqn option in the Docker container.

Running mf2sqn also fails.

When I try to run mf2sqn directly I get the error Accepted value for author is Lang or Burger but neither of these work

I have tried creating Lang.sbt in the mf2sqn/lib/mf2sqn_Submitters/ dir and using "SubmitterGeneric" (to match "mf2sqn/lib/mf2sqn_Submitters/SubmitterGeneric.sbt"). Neither are recognised as valid authors.

For future travellers, you need a .sbt file in $MF2SQN_LIB/mf2sqn_Submitters with a name formatted as 'Submitter[name].sbt` where [name] matches the author arg.

i.e. To use the SubmitterGeneric.sbt template info, run:
mf2sqn -d -t -a Generic -m mfannot_outfile.masterfile
