Bring no-colour option to code snippet printer

Motivation and Context

Ligo compiler error messages return ANSI codes (for colors and bold output) that tools are not able to parse. Thus the need for an option enabling raw output, without ANSI codes.

Description

This MR introduces a new CLI option called --no-colour that is passed to the formatters to disable ANSI printing.
