rst - example CLI for runsync-transfer

  rst gen      --out DIR --profile mixed|large|sparse|manysmall --size 10G
                 [--count N]   (manysmall: number of files)
                 [--data 1G]   (sparse: how many non-hole bytes)

  rst serve    --dest DIR [--addr 0.0.0.0:5555] [--cert-out FILE] [--once]
  rst send     --addr HOST:PORT (--cert FILE | --cert-hex HEX) PATH...
  rst selftest --size 10G [--profile mixed] [--workdir DIR] [--keep]
  rst verify   --a DIR --b DIR
