This is a really good step towards providing the option to switch in custom quadrature rules in the element tabulation. Ref what @IgorBaratta is working on with having more graph-structures on the generated code one could envision a workflow:

  1. Supply custom quadrature rules to FFCx
  2. Feed these quadrature rules into element tabulation (I guess we need a C interface for basix for this)
  3. Feed the tabulated elements into an integration kernel.

This would allow for things such as cutfem quite nicely!
