* fix(simplify): Collect like factors in sums and cancel like terms in sums Since polynomials like `x*(2x+x^2)` are usually written out as polynomials `2x^2+x^3`, adds rules to be more eager to move factors into sums to collect like factors. To complement this, adds a rule extracting negative powers from a sum. Together, these accomplish canceling a common factor in numerator and denominator: (a*k + b*k^2)/k^4 -> k^-4*(a*k + b*k^2) -> a*k^-3 + b*k^-2 -> k^-3*(a + k*b) -> (a + k*b)/k^3 Resolves #1423. * fix(simplify): Adjust for #2394 * chore: Rebase and mark rules with assumptions This commit should update this PR to be fully compatible with the current development mainline. Will remove 'WIP'. * chore(simplify): Additional test cases from PR review Co-authored-by: Jos de Jong <wjosdejong@gmail.com>
