Manually adding GST Interpipe to support Pipewire

[observer-updates]

git clone https://github.com/RidgeRun/gst-interpipe.git
cd gst-interpipe
mkdir build
meson build --prefix=/usr
ninja -C build
sudo ninja -C build install
sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev gtk-doc-tools
(might need a package for meson or ninja, ubuntu will let you know)
last line causes an error but should be fine. use gst-inspect-1.0 to see a list of gstreamer things to check if interpipe is in there
