feat: smear to command line

[sphamba]

Use vim.uv timer intervals instead of timeouts for animation, which doesn't freeze when opening the command line.

Changes

• replace vim.defer_fn(animate, config.time_interval) with timer:start(0, config.time_interval, vim.schedule_wrap(animate))
• remove drawing of previous smear on fast cursor move to avoid random jumps
• add smear to command line and command window

The smear appears when hitting a keybinding that does : ... <cr>, which is not desirable. Events CmdlineEnter, CmdlineChanged, and CmdlineLeave are triggered

@sphamba see :help <cmd>

- Because <Cmd> avoids mode-changes (unlike ":") it does not trigger
  |CmdlineEnter| and |CmdlineLeave| events. This helps performance.

AFAIK any keymap starting with : and ending with <cr> can be replaced with <cmd>. The purpose of <cmd> is to run a command without changing modes after all.

@ColinKennedy I didn't know that, well that solves it :) Thanks!

It's my pleasure! This plugin has just been too much fun not to use!
