Error compiling when importing parameterized type

[zhouxt1]

Hi,

I found this issue when I was trying to compile the NR RRC specification. Here is a simplified example

Foo DEFINITIONS AUTOMATIC TAGS ::=
BEGIN

S1 ::= SEQUENCE {
   c1 SetupRelease { BOOLEAN }
}

SetupRelease { ElementTypeParam } ::= CHOICE {
    release         NULL,
    setup           ElementTypeParam
}
END

Bar DEFINITIONS AUTOMATIC TAGS ::=
BEGIN
IMPORTS
   SetupRelease
FROM Foo;

S2 ::= SEQUENCE {
   c2 SetupRelease { BOOLEAN }
}
END

What happens is the compiler will try to import the SetupRelease from foo in module bar. However, there is no standalone definition of that parametrized type.
So it results in the following error.

error[E0432]: unresolved import `super::foo::SetupRelease`
  --> src/foo.rs:10:9
   |
10 |     use super::foo::SetupRelease;
   |         ^^^^^^^^^^^^^^^^^^^^^^^^ no `SetupRelease` in `foo::foo`

It should be an easy fix.
