This pull request includes the following changes:

• Added a new file format.ts inside the utils directory. This file handles the string formatting of the keyword ranking.
• Implemented color to the terminal output using the chalk package. This enhancement improves the readability and visual appeal of the output. (Closes Colored Terminal Output #3)
• Introduced a loading indicator in the terminal output using the ora package. This addition provides visual feedback to users while the process is running, enhancing the user experience.

These changes aim to enhance the terminal output of the google-rank tool. By adding color and a loading indicator, the output becomes more visually appealing and informative. Users can easily differentiate the ranking results based on colors and have a better understanding of the ongoing process with the loading indicator.
