Removes the given AbstractComponents from the image.

Example:

import { Editor, Erase, uniteCommands, Color4, Path, Stroke, Rect2, pathToRenderable } from 'js-draw';

const editor = new Editor(document.body);
editor.addToolbar();

// Add a large number of strokes
const commands = [];
for (let x = -20; x < 20; x++) {
  for (let y = 0; y < 60; y++) {
    const stroke = new Stroke([
      pathToRenderable(
        Path.fromString(`m${x * 5},${y * 5}l1,1`),
        { fill: Color4.transparent, stroke: {width: 2, color: Color4.ofRGB(x / 10, y / 10, 0.5)}} )
      ]);
    commands.push(editor.image.addElement(stroke));
  }
}
await editor.dispatch(uniteCommands(commands, 100));

---visible---
// Given some editor...

// Find all elements intersecting the rectangle with top left (-10,-30) and
// (width,height)=(50,100).
const elems = editor.image.getElementsIntersectingRegion(
    new Rect2(-10, -30, 50, 100)
);

// Create a command that erases [elems] when applied
const eraseElemsCmd = new Erase(elems);

// Apply the command (and make it undoable)
editor.dispatch(eraseElemsCmd);
