How to update the bindings

Take the updated .gir files (e.g. from your gstreamer main repo checkout) and put them in the gst-gir-files directory
In the gst-gir-files directory, run ./fix.sh
Commit the changes to gst-gir-files and create a commit in gstreamer-rs to update the reference
If there is a new GStreamer version: Manually update gst*/Cargo.toml
Run generator.py
Investigate the diff, fix any mess-ups, look at commented functions and implement them manually
cargo build
for f in (ls |grep gstreamer); cd $f; cargo build --features v1_18; cd ..; end (or with the new version you just added)
Commit your changes to gstreamer-rs
