[ENHANCEMENT] Common `FusionStyle` in matricized `contract`

[mtfishman]

In matricized contract, I think we should determine a common FusionStyle for the arrays involved in the operation and then pass that along in the matricize and unmatricize calls:

TensorAlgebra.jl/src/contract/contract_matricize/contract.jl

Lines 15 to 19 in 6d2a13d

	a_dest_mat = matricize(a_dest, biperm_dest)
	a1_mat = matricize(a1, biperm1)
	a2_mat = matricize(a2, biperm2)
	mul!(a_dest_mat, a1_mat, a2_mat, α, β)
	unmatricize!(a_dest, a_dest_mat, biperm_dest)

. Matricization has a potentially arbitrary permutation or basis, and using a common FusionStyle would help with making sure the matriciziation and unmatrcization is done in a consistent way so the bases are compatible.
