Compact ActivityIndicator animation

[predragnikolic]

Currently the loading animation is a few characters long, [ = ]...

What do you think about a providing a way to have a more compact form like:

The implementation from the video looks like this:

class ActivityIndicator:
    width = 10  # type: int
    interval = 100  # type: int

    _frames = ['⠋', '⠙', '⠹', '⠸', '⠼', '⠴', '⠦', '⠧', '⠇', '⠏']
    
    def render(self, ticks: int) -> str:
        frame = self._frames[ticks % len(self._frames)]

        return "{} {}".format(
            frame,
            self.label
        )

Imo the ActivityIndicator class should take a frames: list[str] parameter that the render method will cycle through. We can then provide helper functions or constants with such frames that a user can choose from or create their own.

The current behavior could then for example be represented by a method that takes a width: int parameter and generates the respective frames .

Unsure if we'd also want to make the position of the label configurable alongside it.
