[Coco] toolshed decb attr TELEWRITER-128

[Arthur Flexser]

I suspect file type 3 was something Tandy invented to apply to files from
its own software like Scripsit or Edtasm source.   I doubt it was ever used
for anything else.  Leaving the file or data type as TW128 stores it would
be appropriate unless you encounter problems with that..
