bug: Associate wav file on installation

[darcywong00]

@terrygibbs said the latest version of SA isn't automatically associating .wav files on Windows 10

Likely need some inno setup changes:

btw, the SA help has steps for the user to register Speech Analyzer for .wav files:
User Interface --> Menus --> File --> "Register Speech Analyzer to open Wave Sound files"
