write me a script in c# for a unity 2d project, that starts "run - vicuna-7b-1.0-uncensored-q4_2.bat", which is located in "C:\Users\USER\Downloads\LLAMA\llama-master-e0305ea-bin-win-avx-x64", and write me a write and read function, which let me acces the "run - vicuna-7b-1.0-uncensored-q4_2.bat" window.
