[feat] update / deprecate

[melMass]

Describe the problem

Deprecate

A lot of things are better done in https://github.com/pythongosssss/ComfyUI-Custom-Scripts/tree/main :

• Math Expression
• String manipulation

Update

• [ ] Check redundant nodes, a lot of things are now builtin to Comfy and should be removed from mtb (https://blog.comfyui.ca/)
• [ ] make a new release (related to #127 )
• [ ] add instructions for the less obvious nodes, proper installation instructions for the optional nodes (for linux, macOS or adventurous windows users)

Add

• [ ] finish the "board" concept
• [ ] a way to tag queue items for a better version of batchFromHistory (compatible with both SDV and AnimateDiff)

Describe the solution you'd like

Just do it
