v1.5.0

• Control output encoding support with --encoding: glyph [default] UTF-8 with private use area icons such as those used by NerdFonts; utf8 only standard UTF-8 without private use area; ascii only ascii characters. Designed to replace the --ascii arg, this remains but hidden.
• Colour control made similar to other programs with --color/--colour: auto [default] show colours if the output goes to an interactive console; always always use colour escape codes; never never use colouring. --no-color remains but is hidden and one can also still use the NO_COLOR env.
• Icon control for pairing with --encoding, --icon: auto [default] show icon blocks if the --encoding supports icons matched in the icon theme; always always show icons if included in icon blocks; never never print icon blocks. There is also the hidden --no-icons to drop the icon theme completely.
• Updates to Cargo packages.
