bug(generator): cannot generate when go 1.18+ generics are used. #159

Generator blows up really hard on generics, would be nice to handle.

Currently, decodeASTStruct does not consider TypeParams of ast.TypeSpec. That's why structs with generics cannot be generated. To support generics, I think fastssz also needs to decode TypeParams.

Do you have an elaborated set of examples on how do you want to use generics? I am trying to understand the full scope. The example in #160 should be fairly easy to handle in itself.

This is a fix to encode the struct in #160.
