Simply plays a sound whenever you open a configured workspace.
[!IMPORTANT]
On Windows, this uses powershell to play the sound.
On OSX, it uses afplay.
On Linux, this uses the sox package's play command, so make sure
to have it installed and in your PATH for this extension to work.
Configuration
Configuration is done manually through your settings.json. Example:
The keys of soundWorkspaceMap are RegExp patterns matching the workspace URI,
and the values are absolute filepaths. Files should ideally be .wav, .mp3 or
.ogg, I cannot guarantee platform compatility for any other filetype.
