This has been live since July but I think I never "formally" announced it.
@chrichri no pbuilder involved for l5-fetc-hnext.
That's just a bunch of things `librem5-dev-tools` pulls in to ease development. We can move them to recommends.
The script really just downloads things and installs them via `dpkg -i`. Note that for #phosh you also need phoc-next libwlroots10 from octarine.
If you're running #PureOS you can install `l5-devscripts` on your device and then just do:
```
l5-fetch-next phosh-byz
```
and it will fetch the latest #phosh-next Debian package from CI and install it for testing.
