Replay Gain - MP3Gain / AACGain insecure & no longer supported

[kekkc]

Hi,

SoundKoverter is fantastic, however I realized a small issue:
MP3Gain & AACGain were removed by kubuntu, because they are no longer maintained & propably insecure ( https://ubuntuforums.org/showthread.php?t=2276186 ).

However, there seems to be a better alternative: python-rgain.

Is there any plan to support this?

I suggested to include bs1770gain (#61) which is currently being maintained (python-rgain apparently isn't).
