'which' is not available on Windows

Line 22 in 4423e0e

 process.execSync(`which mutagen`); 

An equivalent is "where.exe" (the .exe is important)

Hi, I added this fix in v1.0.9, but as I do not have a Windows machine available right now I cannot test this. Could you try and verify that it works? For now I will close this issue but it can be reopened if it is found to not work.
