Support for conversion and quantization scripts from llama.ccp

**Is your feature request related to a problem? Please describe.**

This is more a question. I'm using llama.cpp to convert a pytorch model and quantize it and this requires access to the `convert.py` and `quantize` files in the original llama.cpp repo. I could use git-submodules for that but it would be nice to simply add a dependency to my project and have access to this functionality. Is this somehow available to the current setup of this lib ?

**Describe the solution you'd like**
Copying the aforementioned scripts to the installed location of this lib.

**Describe alternatives you've considered**

Using git-submodules.
