Segmentation and AnyWidget project edits

[gnodar01]

• modify the language to be more generalized and less specfic to YOLACT, AnyWidget, and Juypter
• highlight that one of the goals of the segmentation project is to have fine-tuning capabilities in the browser

Probably best to move the AnyWidget project size to medium or medium/large. Creating the widget integration itself is medium, and then building out the API to handle all the interactions to/from Piximi we want would increase the scope to large.
