[Feature Request] Allow custom launch commands

[Vixeliz]

With custom launch commands what can be done with acode could be more flexible. The android activity manager can be used to do this. A common place you see it used is in emulation frontends however it could also be useful here to launch directly into an application. For example love2d soon will support saf which means you could edit the lua files in acode then launch directly into love to test if activity manager was supported. Especially if you allowed passing arguments to the activity manager such as a contenturi or a path. I think it would be incredibly useful and not the hardest thing in the world to implement
