Suggestion: add cli args for setting hud, esync, and retina mode

[janeklb]

It would be convenient to not have to manually set the hud/esync/retina mode settings every time orion is launched.

One way this could be achieved is by adding support for cli args that control these settings:

eg.

• --hud (and --no-hud)
• --esync (and --no-esync)
• --retina-mode (and --no-retina-mode)

setting any of those options would then bypass the corresponding prompt (https://github.com/andrewmd5/orion/blob/main/orion/Program.cs#L111-L113)

with this users could set up an alias with their preferred execution mode

eg.

alias orion="orion --no-hud --esync --no-retina-mode"
