Create cleaning scripts for text, image, video, and csv files

[Jim Schwoebel]

Specify cleaning scripts for each of these.

• text - if abnormal number of characters, do not process
• image - if image is too big of a size (e.g. size)
• video - if video is too big of a size (e.g. <1 min)
• csv - if csv has too many columns or does not compute only numerical or categorical values, do something
