Set up wezterm to continue to use Iosevka for everything *except*
italics (in all weights) which will instead be displayed by the Victor
font.
This ultimately results in cursive fonts for italics and Iosevka for
everything else, very pretty.
Switching from my custom, brittle, styling implementation `styler` to
the wonder `flavours` program which does exactly the same only with more
clarity, faster and - I would presume - more stable.
Split the lists into two, with testing getting automatically updated on
packages added (and removed, but only if the package to be removed is
*not* in stable packages already).
This way, I can always be sure that I have my stable setup in the
repository, but packages that I am temporarily testing have a place
without being forgotten and I can more easily change them around until
they find a place in stable or get thrown out.
