[Feature Request] Remember volume or command-line volume option.

[LupinePariah]

I have sensitive ears (hyperacusis), so I tend to use Munt with things that have inherent mixing problems (like DosBox-Pure, where you can't really change the MT-32 mixing with the MIXER command due to its implementation). I don't want music blasting my ears out when I'm trying to focus and listen to voice samples.

I've been doing pretty good about making sure I set Munt's volume low enough when I start it but I'm worried about when I won't—because that's tinnitus country! I couldn't find any documentation regarding this, so I figured I'd ask. Just being able to set the volume on the command-line is fine too because shortcuts, any way to have it start at a volume that isn't 100%.

As far as I get the problem, it doesn't seem like we are concerned about the "Master Volume" setting of the mt32emu engine here. This is because it is programmable via SysEx messages, and resetting its value to the default is what often happens at start of a game / tune. Therefore, I'd suggest using another means of controlling the output level.

There is a couple of settings "Output Gain" and "Reverb Output Gain", and these can only be altered via the UI or the dedicated API. Besides, these allow both lowering and amplification of the output to some degree. In mt32emu-qt, you can find them in the Synth -> Properties dialog, and they are saved in the synth profile so to persist restarts.
