Add a way to collect intermediate pattern replacements when simplifying

Add a way to collect intermediate pattern replacements when simplifying.
e.g.
Input: x^(-1)/(y/z)
Output[0]: x^(-1)*z/y // any1 / (any2 / any3) -> any1 * any3 / any2
Output[1]: 1/x*z/y // Powf.PHang(any1, Num(-1)) -> 1 / any1
...

Currently only the entities can be get but not the patterns used.

There's Entity.Alternate which returns some possible forms of the initial expression.
Or you mean step-by-step simplification?

[Happypig375]

step-by-step simplification?

Yes

[WhiteBlackGoose]

No point of adding it, to be honest. The way simplification works is not the one we are taught in schools so it would be garbage for the user. It's very unobvious and complicated

[Happypig375]

Okay
