feat(wm): add container resizing

The last remaining feature to bring komorebi to feature parity with
yatta. Implementing this in komorebi was a lot harder because I had to
make sure that resizing worked even when the layout is flipped (in any
one of the three possible ways).

In yatta, resize dimension information was stored on the window. In
komorebi, I initially tried storing this information on the Container
itself, but eventually decided to store it for all Containers in the
Workspace.

There is some additional work required to ensure that this Vec is kept
up to date whenever containers are added or destroyed, but it all seems
to be working fairly well.

I got rid of the iterative fibonacci code that I adapted from leftwm and
went back and reworked the recursive code that I was using in yatta
(originally from umberwm I think) to integrate layout flipping. At least
for me, it is much easier to reason about.
