Rotation Angle Zero doesn't work on marker update

[FernandoI7]

Describe the bug
When a marker is defined with rotationAngle equal to zero, after updating, the marker does not use the zero value and updates the marker angle considering the position variation.

To Reproduce

1. Setup a marker with rotationAngle={0}

import { useEffect, useState } from "react";
import { LeafletTrackingMarker } from "react-leaflet-tracking-marker/src";
import PropTypes from "prop-types";

const AnimatedMarker = ({ icon, latitude, longitude, children }) => {
  const [prevPos, setPrevPos] = useState([latitude, longitude]);

  useEffect(() => {
    if (prevPos[1] !== longitude && prevPos[0] !== latitude)
      setPrevPos([latitude, longitude]);
  }, [latitude, longitude, prevPos]);

  return (
    <LeafletTrackingMarker
      icon={icon}
      position={[latitude, longitude]}
      duration={1000}
      rotationAngle={0}
      rotationOrigin="unset"
    >
      {children}
    </LeafletTrackingMarker>
  );
};

AnimatedMarker.propTypes = {
  icon: PropTypes.object.isRequired,
  latitude: PropTypes.number.isRequired,
  longitude: PropTypes.number.isRequired,
  children: PropTypes.object.isRequired,
};

export default AnimatedMarker;

2. Update the marker position

Expected behaviour
Marker must keep zero angle even after marker position update
