fix: extension support #3
Description
In caselyjs v1.0.1, it became a CLI.
But it has still some limitation like-
By default it operates on .js, .jsx, .ts, .tsx files.
If codebase contains any other files with different extentions. It ignores that which is fine so that it will not operate on essential json files or config files .
There must be a config file which will contain all the necessary files name and directories name that should be avoided by default.
Accross different different environments of codebase eg. a codebase can be a nextjs, vitejs, vuejs, django, flask, springboot etc.
Also it can contain some dependency specific files eg. .eslintrc .prettierrc, nodemon.json etc.
It should provide --ext . for accessing all the files within the directory excluding blocked files in the above.
