3 Assistants, Compatibility for Visual Studio 2019 and 2022

Modernized solution to generate 2019 and 2022 compatible extension packages.
I also added two more assistants, Merlin and Genius.
Extended the package to not only support single-layer animations (Clippy), but also up to three layer animations (Genius). A few bug remain, some animations have a few hickups.
Code also now includes an AssistantBase class, and code to much quicker migrate/parse animation files for other assistant (future).

Lots of code cleanup, and changes also submitted to Eros's repo (no response yet). All this couldn't exist without the inital effort from Eros Fratini (https://github.com/tanathos/ClippyVS)
.

Future plans:

• Unit Testing / Code Coverage
• More Code Cleanup
• Adding more assistants
• Fixing present animation hickups
