Simple Captcha

I was trying to get the CICD pipeline work the last whole week ;-;
I also did some updates to this project too:

• Set up the CI/CD pipeline
• Created the README file
• Create the Releases

Added API part :D

I have done the CLI part. I switched to click for more easy-to-read code :D
I also restructure my code so I can publish it as a package

I have done the DB part
I also wrote the definition of the CLI

The audio part is also done :D
But the level 5 is kinda broken I guess

I have completed the text captcha.
I use pillow and numpy for this text generation
It has 5 level with increasing difficulty. As shown in the image below from left to right, from top to bottom, there are 5 levels in order.
