added feature to extract all images from the pdf #44

[shebinleo]

Extract all embedded images from PDFs.

// From file path
const imagePaths = await pdf2html.extractImages('path/to/document.pdf');
console.log('Extracted images:', imagePaths);
// Output: ['/absolute/path/to/files/image/document1.jpg', '/absolute/path/to/files/image/document2.png', ...]

// From buffer
const pdfBuffer = fs.readFileSync('path/to/document.pdf');
const imagePaths = await pdf2html.extractImages(pdfBuffer);

// With custom output directory
const imagePaths = await pdf2html.extractImages(pdfBuffer, {
    outputDirectory: './extracted-images', // Custom output directory
});

// With custom buffer size for large PDFs
const imagePaths = await pdf2html.extractImages('large-document.pdf', {
    outputDirectory: './output',
    maxBuffer: 1024 * 1024 * 10, // 10MB buffer
});
