Support struct type with generic type params used in fields

[SamuelQZQ]

For example, struct Element has generic type params T0 and T1, and T0 T1 is used for the type of the struct fields.

{
      name: "Element",
      is_native: false,
      abilities: ["copy", "drop", "store"],
      generic_type_params: [
        {
          constraints: [],
        },
        {
          constraints: [],
        },
      ],
      fields: [
        {
          name: "key",
          type: "T0",
        },
        {
          name: "value",
          type: "T1",
        },
      ],
    },

Currently Surf cannot inference those fields type correctly.

I have the same request. Is there a way around it? Or any way to do this using aptos-sdk?
