disable_auto_save and disable_mouse CLI flags should have been kebab-case

[SanchithHegde]

I noticed this when checking the output of the help message:

      --disable_auto_save                   Disable to save automatically
      --disable_mouse                       Stop handling mouse events

I believe the --disable_auto_save and --disable_mouse flags should have been kebab-case (--disable-auto-save and --disable-mouse respectively) to maintain consistency with the rest of the CLI flags.

This can be easily fixed by updating the value specified for long = "..." in two lines:

• viddy/src/cli.rs

  Line 110 in ad1f0fe

  long = "disable_auto_save",

• viddy/src/cli.rs

  Line 116 in ad1f0fe

  #[arg(long = "disable_mouse", help = "Stop handling mouse events")]

In case any other contributor is interested, they can go ahead and open a PR to address this, I don't mind.
