Fonts: Roboto Mono

[DevCharly]

This PR packages the Roboto Mono font (https://fonts.google.com/specimen/Roboto+Mono) into a JAR (will be released to Maven Central later) and provides an easy way to use it with FlatLaf.

The font need to be installed before it can be used.

For lazy loading use:

FlatRobotoMonoFont.installLazy();

Or load immediately with:

FlatRobotoMonoFont.install();

To use Roboto Mono as monospaced font in your application, use:

FlatLaf.setPreferredMonospacedFontFamily( FlatRobotoMonoFont.FAMILY );

FlatLightLaf.setup();

//TODO create UI

You can of course also create fonts. E.g.:

// basic styles
new Font( FlatRobotoMonoFont.FAMILY, Font.PLAIN, 12 );
new Font( FlatRobotoMonoFont.FAMILY, Font.ITALIC, 12 );
new Font( FlatRobotoMonoFont.FAMILY, Font.BOLD, 12 );
new Font( FlatRobotoMonoFont.FAMILY, Font.BOLD | Font.ITALIC, 12 );
