command line parameter to control pre/post pause

[sassman]

context

• sometimes at the end of a gif there needs to be a pause, in order to calm down, and not get a crazy fast spinning back dizziness.
• Also on the other hand before things get to the point too fast, it can be beneficial to have a little grace time where the user would see the first frame for seconds before the animation / video would start.

proposal

1. a --end-pause | -e to specify the post / end pause time, that is the time in seconds that the gif / video will show the last frame.
2. a --start-pause | -s to specify the pre / start pause time, that is the time in seconds that the first frame will be shown

do you think that full seconds might be enough? Or better going for milli seconds?

Wonder if you could use humantime to let it be flexible? https://docs.rs/humantime/2.1.0/humantime/
