Comment:
I have started to create a package for this already but abandoned it. Here is that as of now. It's installed to /usr/local but xbps does not allow that.
```sh
# Template file for 'libsixel'
pkgname=libsixel
version=1.8.6
revision=1
build_style=configure
#configure_args="--with-libcurl --with-gd --with-gdk-pixbuf2 --with-jpeg --with-png --with-pkgconfigdir --with-bashcompletiondir --with-zshcompletiondir --enable-python --enable-debug --enable-gcov --enable-tests"
hostmakedepends="pkg-config"
short_desc="A SIXEL encoder/decoder implementation derived from kmiya's sixel"
maintainer="*** <***>"
license="GPL-3.0-or-later"
homepage="https://github.com/saitoha/libsixel"
