This is the main game loop and it will preserve state, do checks.

Essentially the main function handles initialization of the tool by parsing flags, initializing tcell, and handig off parameters to the game director.

The game director listens for the events:

Resize: pause the game, show an error when the terminal dimensions are smaller than 80x24
Keypress: space to (un)pause, WASD/^ to handle direction, q to (rage) quit
Time-passed: Move the snake into the given direction

This needs some testing.

I have added a game director, and it doesn't work. tcell doesn't seem to have a time event I can listen to next to key presses and resizes, so I will need to split this up. There is this https://github.com/gdamore/tcell/blob/v2.6.0/event.go#L30 and *EventTime.SetEventTime(t time.Time), but this doesn't seem to fit the bill.

So this is going to be go routine, channel and a function.

keypresses := make(chan int, 10)
go gameDirector(keypresses)
handleKeyBoardEvents(keypresses)

Line 1: Create the channel to communicate key presses between processes.
Line 2: This controls the direction of the snake, and placement of the apple.
Line 3: intercepts keyboard presses and either pauses, or sets the direction of the snake

For #1 split the gameplay loop up from the key processor. Non-blocking channels proof of concept.

This is working as intended. Now to add tank-controls.
