Reference enums in external file?
Hi guys,
I'd like to reference an enum (*rowing_messages::position* in this case)  from external file. For external types it seems it's enough to add "rowing::" prefix, but for enums it doesn't seem to work. Is there any way?

base file (test.ksy)
```
meta:
  id: test
  imports:
    - rowing
  endian: be
  
seq:
  - id: system_id
    type: u1
  - id: data
    type:
      switch-on: system_id
      cases:
        rowing_messages::position: rowing::rowing_position_message
```

the "external" file (rowing.ksy):
```
meta:
  id: rowing
  endian: be
  
enums:
  rowing_messages:
    0x10: position
    0x12: meter_per_stroke
  
types:
  rowing_position_message:
    seq:
      - id: id
        type: u1
      - id: timestamp
        type: u4
```
