- module instances with modport bindings are now inlined
- support for modports in generate loops
- support for generic interfaces
- implied modport instance propagation
- add error message for interface instances missing port list

- interface conversion only waits for type resolution of modports
- typeof conversion resolves struct field accesses
- logic conversion only converts logic data declarations
- struct conversion only converts within modules
- fix nested type traversal order causing premature struct conversion
