Error on .msg files when using openmcdf 3+

[bloflan1]

Works with OpenMcdf 2.4.1, but not 3.0.3. Getting "Could not load type 'OpenMcdf.CompoundFile' from assembly 'OpenMcdf" on .msg file type. Other types seem to work okay.
Maybe restrict to openmcdf >= 2 < 3?

Looking at their release notes, the API has been rewritten and the CompoundFile class no longer exists in v3.

I'd prefer to support the newer version if possible, I'll have a look into it and update our code to support it.
