Subject: [PATCH] Add DWM logo on left bar before tags

This patch adds a DWM logo to the left side of the status bar, positioned
before the tags, for aesthetic or branding purposes.

Defines a fixed logo width (`dwmlogowdth = 54`) and adjusts tag rendering to
prevent overlap.

Uses multiple `drw_rect()` calls to render a pixel-art style "dwm" logo using
rectangles.

This patch is purely visual and does not impact DWM's core functionality or
performance. It may appeal to users who want a more personalized or distinctive
appearance for their window manager.
