* config: introduce a custom value type for layout related options
* widgets: use CLayoutValueData for size and position options
* widgets: catch bad_any_cast and out_of_range when contructing widgets other than label
* config: rename and restrict CLayoutValueData::fromAny to fromAnyPv
This is only for casting `any` variables that represent a void * to a
CLayoutValueData*, not just any any.
* misc: remove debug prints
* misc: use Vector2D, Box and Mat3x3 from hyprutils
* nix: flake update
Fix CI fails. We need hyprutils>=0.2.3
* misc: use a function to convert Hyprlang::VEC2 to Vector2D
* misc: fixup some includes
* label: move asset updates out of the draw function
This allows us to check if the label has actually updated after the
callback from the asyncResourceGatherer. If it isn't we can requeue the
renderUpdate() function.
