Allow .vintageousrc to map any keybinds

[mreq]

It'd be nice if we were able to perform a custom-bound shortcut

Say I'd like to trigger a command, which is bound to ["ctrl+g", "s"] in sublime keymaps. To remap that via .vintageousrc one'd write:

map <Leader>gs <C-g>s

I can do something similar using the leader key (space in my case) in the actual sublime keymaps, but that breaks vintageous a bit (for instance movement towards space (f" ") doesn't work, etc.).
