Speed labels on segments would be useful

[git-hub-user]

When constructing a speed curve in slowmo UI, it would be useful to have labels indicating the speed (slope) of that segment.
For me, the speed relative to the original frame rate would be most useful. E.g. 1x, 4x, 0.25x, etc.
I suppose this is only straight forward for linear segment. For bezier segments speed would vary (although I did not yet manage to get a 'grip' on bezier node handles) along the segment, but the average speed between two nodes is easy enough to calculate.

Hi @git-hub-user, thanks for your report! Definitely makes sense. Please report it on https://github.com/slowmoVideo/slowmoVideo/issues where slowmoVideo is now actively developed :) Thanks!
