Title:
  dd reporting 0 B/s

Status in rust-coreutils:
  New
Status in rust-coreutils package in Ubuntu:
  New

Bug description:
  The uutils version of dd will report 0.0 B/s if the bandwidth of the
  data is under roughly around a KB, it should be reporting the correct
  amount of bandwidth instead.

  You can test this with pv:

  $ pv -q -L 256 /dev/urandom | dd of=/dev/null status=progress
  3840 bytes (3.8 kB, 3.8 KiB) copied, 15.0834 s, 0.0 B/s^C

  As you can see, uutils is reporting 0.0 B/s even though it should be
  saying ~0.25 kB/s.

  If you try this with gnudd, it works as expected and returns 0.2 kB/s:

  $ pv -q -L 256 /dev/urandom | gnudd of=/dev/null status=progress
  3584 bytes (3.6 kB, 3.5 KiB) copied, 15 s, 0.2 kB/s^C
  0+154 records in
  7+0 records out
  3584 bytes (3.6 kB, 3.5 KiB) copied, 15.3901 s, 0.2 kB/s
