### Description
This patch is based in
[client-opacity](https://codeberg.org/dwl/dwl-patches/raw/branch/main/patches/client-opacity/client-opacity.patch)
patch. Add different opacities level if the client is focus or not.
The opacities levels can be change by short cuts.
```
[MODKEY]+[Ctrl]+[k] -> increase focus opacity
[MODKEY]+[Ctrl]+[j] -> decrease focus opacity
[MODKEY]+[Ctrl]+[Shift]+[k] -> increase focus opacity focused client
[MODKEY]+[Ctrl]+[Shift]+[j] -> decrease focus opacity focused client
```
