docker container should look for files in base bucket and job id folder (where job id is druid-v3 pair), e.g. "s3://sul-speech-to-text-staging/nj873rz3527-v2"
docker container should place completed files in a subfolder called "out" in the same place the input files came from, e.g. "s3://sul-speech-to-text-staging/nj873rz3527-v2/out"
