* move crates into a 'crates' folder
* added cargo-about to check dependency licenses
* create ggml-sys bindings and build as a static library.
simple addition sanity test passes
* update licenses
* yeet alice
* yeet qa model
* yeet fact model
* [wip] idiomatic rust bindings for ggml
* [ggml] mul, add and sub ops implemented for tensors.
i think it would be easier to try and implement a bert model in order to figure out which ops we should include in the binding. for instance, is view and concat needed?
