Create colored output functionality

[ojasmaheshwari]

We need to associate colors with information, warning and error logs. To do this, make an AsciiColor class in the project which is responsible for outputting text with a specified color into the terminal. It can be used similar to the following examples:-

std::string yellowText = AsciiColor::colorized("This text will be visible in yellow\n", Color::Yellow);

Use ANSI Escape codes for colors for now
