AlignmentGeometry is unused

[awhitford]

I noticed that many classes have a property like this:

Animated-Text-Kit/lib/src/typer.dart

Lines 45 to 48 in 002484c

	/// Adds [AlignmentGeometry] property to the text in the widget.
	///
	/// By default it is set to [AlignmentDirectional.topStart]
	final AlignmentGeometry alignment;

However, it is not used.

As a result, I recommend removing it to avoid confusion.

This impacts:

• Colorize
• Fade
• Scale
• Typer
• Typerwriter

@aagarwal1012 Can we get away with removing this all at once? Or should we leave a @deprecated parameter for a release to warn people? (Since it was not used, I'm leaning towards just removing it altogether.)

@awhitford, let's remove this unused parameter and create a new release.

This parameter is used only by RotateAnimatedTextKit. I'll submit a PR in a second.
