Add a transient map for frequent commands

[magne-hov]

Hi, thanks for this nice package.

I like to invoke smudge-command-map with a prefix key, but that means that I need quite a few key presses if I want to skip multiple tracks or change the volume by multiple increments.

I find that a transient keymap solves this pretty well for me. It lets me define frequent commands that I can repeat without needing to repeat the prefix. While the transient map is active any other key will work as normal and deactivate the transient map. This is the same way that test-scale-adjust lets you repeat itself without repeating the C-x prefix.

I've added a defcustom so that this feature can be enabled optionally:

(use-package smudge
  :custom
  (smudge-player-use-transient-map t)
  :bind-keymap
  ("C-c M-s" . smudge-command-map))

I thought I'd share this here in case other were interested in having similar functionality.

I was wondering about something like this just the other day. Thanks for sharing!
