Fix loading plugins expecting COM to be available

The `LoadLibrary()` call for PSPaudioware InfiniStrip would fail because
the plugin would always expect COM to be initialized. Now if loading a
VST2 or VST3 module fails, we'll initialize COM and try again before
throwing an error. This may fix #94.

 ### Fixed
 
+- _PSPaudioware InifniStrip_ would fail to initialize because the plugin expects
+  the host to always be using Microsoft COM and it won't initialize it by
+  itself. InfiniStrip loads as expected now.
 - Prevent _Native Instruments' FM7_ from crashing when processing MIDI. As a
   fix, MIDI events are now deallocated later then when they normally would have
   to be.
