[Feature] Remove and merge redundant items

[timerring]

Is your feature request related to a problem? Please describe.

The logs used for recording the result of emoji removal are redundant and can be consolidated into one log.
And the merging clips in hours maybe useless when the account meet the bilibili requirement which can upload oversize videos.

Describe the solution you'd like

Merge remove logs into a single log.
Add the default option to merge the videos in days.
