Add percentage labels to volume and brightness indicators

[Ferdi265]

This PR adds a textual percentage next to the progress bar in the volume and brightness indicators. This is useful for users who still want to know the exact volume percentage set in practice.

This is off by default and can be enabled with the show_percentage boolean setting in the [server] block in CONFIG_HOME/swayosd/config.toml.

Example config:

# ~/.config/swayosd/config.toml
[server]
show_percentage = true

I'd also prefer if the user could disable this. Might wait with this until config support has been added to undo some of the cmdline arg clutter

Yes, that is my thought as well. I'm completely fine with leaving this PR hanging until config support is added, I might even help with implementing config support if I find time.

Rebased on top of #79 and added a configuration option to enable percentage display.

[ErikReider]

I'll wait until #79 is merged :)

[Ferdi265]

rebased onto the merged config branch and updated the PR description.

@ErikReider if you'd like to reduce the number of things in the CLI options I can also remove the CLI option added in this PR (I already have a fixup commit for that locally, I'd just need to push it)
