Refactored method for loading rule tooltip images, new Equivalence sub category, adjacency generalization, updated quantifier parsing and split quantifier distribution

[zacharybonagura]

• Refactored the function that loads images for each rule to ensure optimization in program so images are only loaded once. Additionally, regrouped all equivalence rules into one sub category named "Equivalence".
• Fixed glitch where quantifiers would distribute across multiple expressions, now only distributes over single Expr, whether it's one term or multiple wrapped in parenthesis
• Added adjacency generalization to support nested operations
• Split Quantifier Distribution into two separate rules, one Quantifier Distribution under Quantifier Equivalence, the other Quantifier Inference under Misc. Inference
• Updated rule images and package dependencies
