[CUETools.Codecs.FLACCL] Fix constructor

The constructor parameters of Activator.CreateInstance() were updated
in CUETools.Processor\AudioReadWrite.cs as of commits 16fccfe and
e1f8906. The parameter "settings" was added in front of path and IO,
which required an update to the order of constructor parameters in
several codecs.

- Fixes the following error message, when using FLACCL codec:
  Exception: Constructor on type
  'CUETools.Codecs.FLACCL.AudioEncoder' not found.
- This is a follow-up commit to 18c6c1a
- Resolves #82
