Diff since v0.17.0

• Added an optimize function that takes an expression and returns the optimized expression, using EGraphs from Metatheory.jl
• symbolicegraph function to construct an egraph prepared for <:Symbolic expressions.
• Internal function toterm to transform Add, Mul, Pow, etc... into Term{T}
• Internal function unflatten that takes associative n-ary terms and turns them into their binary Term{T} representation (egraph rewriting works best with this representation)
• An egraph cost function that computes the cost of operations of terms in CPU cycles (See https://arxiv.org/abs/2105.03949).
• similarterm for <:Symbolic types can now dispatch against a f::Symbol operation, resolving the corresponding function object to support the EGraph backend
