When initialising the package with an input file, the program does not check the file for tailwind directives before prepending the required directives to the file.

Steps to reproduce:
create a base.css file in the root directory
input the required tailwind directives i.e

@tailwind base;
@tailwind components;
@tailwind utilities;

in the base.css file

run
tailwindConfig init -i base.css

in your terminal

You will find that the base.css file has a duplicate entry of the tailwind directives. 👇🏾

@tailwind components;
@tailwind utilities;
@tailwind base;
@tailwind components;
@tailwind utilities;
@tailwind base;
