Fix clear() method return value

[lumirlumir]

Hello,

While the documentation mentions that the clear() method returns the instance, it doesn't actually do so. This causes an error when attempting to use method chaining, as shown in the example below:

spinner.clear().stop();

To fix this, I modified the clear() method to return this, enabling method chaining. I also followed the formatting style used in the start() and stop() methods.

• For reference, here is the formatting used in the start() and stop() methods:
  

  yocto-spinner/index.js

  Lines 64 to 100 in 4e18542

  	start(text) {
  	if (text) {
  	this.#text = text;
  	}
  	if (this.isSpinning) {
  	return this;
  	}
  	this.#hideCursor();
  	this.#render();
  	this.#subscribeToProcessEvents();
  	this.#timer = setInterval(() => {
  	this.#render();
  	}, this.#interval);
  	return this;
  	}
  	stop(finalText) {
  	if (!this.isSpinning) {
  	return this;
  	}
  	clearInterval(this.#timer);
  	this.#timer = undefined;
  	this.#showCursor();
  	this.clear();
  	this.#unsubscribeFromProcessEvents();
  	if (finalText) {
  	this.#stream.write(`${finalText}\n`);
  	}
  	return this;
  	}
