picture component always using default sizes

[robiiiiiiiiiiiin]

Describe the bug
When using the picture component, if we set custom deviceSizes, the sizes used in the <source> tag are still the default sizes.

To Reproduce
Add custom deviceSizes in next.config.js

const withExportImages = require('next-export-optimize-images');

module.exports = withExportImages({
  output: 'export',
  images: {
    deviceSizes: [300, 430, 600, 768, 1024, 1536, 2048, 2560],
    imageSizes: [],
  }
})

Use the picture component

import Picture from "next-export-optimize-images/picture";
import test from "@public/images/test3.jpg";

const Home = () => {

  return (
    <div>
      <Picture src={test} alt="test" sizes="100vw" />
    </div>
  );
}
export default Home

The result is the following

<picture>
    <source
        srcset="/_next/static/chunks/images/_next/static/media/test3.d0fd0ba6_640.webp 640w, /_next/static/chunks/images/_next/static/media/test3.d0fd0ba6_750.webp 750w, /_next/static/chunks/images/_next/static/media/test3.d0fd0ba6_828.webp 828w, /_next/static/chunks/images/_next/static/media/test3.d0fd0ba6_1080.webp 1080w, /_next/static/chunks/images/_next/static/media/test3.d0fd0ba6_1200.webp 1200w, /_next/static/chunks/images/_next/static/media/test3.d0fd0ba6_1920.webp 1920w, /_next/static/chunks/images/_next/static/media/test3.d0fd0ba6_2048.webp 2048w, /_next/static/chunks/images/_next/static/media/test3.d0fd0ba6_3840.webp 3840w"

        src="/_next/static/chunks/images/_next/static/media/test3.d0fd0ba6_2560.jpg">
</picture>

In the srcset of the <source> tag, the following sizes are used [640, 750, 828, 1080, 1200, 1920, 2048, 3840] instead of [300, 430, 600, 768, 1024, 1536, 2048, 2560] as set in next.config.js. And the image files are only generated with the following sizes [300, 430, 600, 768, 1024, 1536, 2048, 2560] so it causes a 404 error.

Expected behavior

Thank you for the library !
