feature/extract_file_paths

[anuk909]

Add the function extract_file_paths that find paths based on simple regex instead of query. I think that it should be accurate as much as specify_file_paths and save one query. It's possible to add "allowed_extenstions" and "forbidden_extenstions" to improve it even more (And maybe in the future make this extenstions language dependant when smol-ai will be able to write code in more programming languages). It's still possible to use specify_file_paths so no code will break (I think)
