Setting custom mouse cursor in miracle-wm

[mecattaf]

Currently in sway I have the following in my config to customize the mouse cursor:

seat seat0 xcursor_theme Bibata-Modern-Classic 24
seat seat0 fallback true

set $gnome-schema org.gnome.desktop.interface
exec_always  {
        gsettings set $gnome-schema cursor-theme 'Bibata-Modern-Classic'
      	gsettings set $gnome-schema cursor-size '24'
}

Sway actually relies on both xcursor and gsettings for the cursor control.
In Hyprland they improved this by introducing hyprcursor, a more efficient cursor format. From their docs:
"Notable advantages over XCursor

• Automatic scaling according to a configurable, per-cursor method.
• Support for SVG cursors
• Way more space-efficient. As an example, Bibata-XCursor is 44.1MB, while it's 6.6MB in hyprcursor."

Whether or not you want to use it and its associated hyprcursor-util please support xcursor and gsettings cursor in miracle-wm.

I believe that Mir has support for CursorThemes, which would be what we want here. However, I don't think they are dynamic, which is what I would want. Still, it is worthwhile adding to miracle :)
