Record/playback options to match asciinema

[johngarner-dwp]

Would be great if PowerSession could record/playback with the IDLE_TIME_LIMIT functionality asciinema has?

asciinema play --help
usage: asciinema play [-h] [-i IDLE_TIME_LIMIT] [-s SPEED] filename

positional arguments:
  filename              local path, http/ipfs URL or "-" (read from stdin)

options:
  -h, --help            show this help message and exit
  -i IDLE_TIME_LIMIT, --idle-time-limit IDLE_TIME_LIMIT
                        limit idle time during playback to given number of seconds
  -s SPEED, --speed SPEED
                        playback speedup (can be fractional)

Understand this can be done through the asciinema website staged cast files, but to have it locally would very helpful.
