This is a feature I started working on long ago for Hanami: hanami/hanami#906

There could be two parts to this:

• Colorizing the output of dry-cli, like each command's help and the list of subcommands
• Adding something like say that users of the library can use to print in color (instead of using print).

e.g.

say "create", color: :red

This should probably be like print rather than puts (no trailing newline), since people should be able to print in several colors on one line.

The concrete use-case for this could be like hanami/hanami#906, being able to colorize the output of file generation for Hanami.

Is this something we'd be interested in adding to dry-cli? Any thoughts on the API?
