The basic functions are all working properly. Now the model works by
using diesel to connect the sql database and retrieve all the items
and organize them. Then it'll ensure any additions and deletions are
correct and happen first on the database before adding them to the
model.
There is still a C++ proxyModel inbetween QML and Rust, but
this proxyModel interfaces with the Rust model instead of the C++
SqlTableModel.
Updated a lot of things to include ffmpeg_6-full so that we can use
some of the latest ffmpeg features and include ffmpeg-next in our rust
project.
Then some of the environment pieces were missing for ffmpeg-next to build.
This object is still unfinished, but it will later serve as our main
object to connect to for the slides that are shown on screen. All of
this needed some heavy tweaking and I still need to learn more about
rust, but the beginnings are there and it will be worth it to have the
safety and speed that rust provides
