feat: tweak whisper to use local whisper.cpp instance

[hezirel]

I made some changes to the whisper.lua file
Now by building whisper.cpp
Starting the server using the command
./server -m models/ggml-distil-large-v3.bin --convert

And set your config.whisper.endpoint = "http://127.0.0.1:8080/inference"
You can now use fully local whisper, it runs so well on silicon it's incredible
