feat: add TIFF conversion options and integrate wasm-vips for image processing

- Updated README.md to include new dependencies: wasm-vips, pixelmatch, diff, and microdiff.
- Added wasm-vips to package.json and package-lock.json for advanced TIFF encoding.
- Enhanced localization files with new options for DPI, compression, color mode, and multi-page TIFF saving.
- Implemented UI changes in pdf-to-tiff.html to allow users to select DPI, compression type, color mode, and multi-page options.
- Refactored pdf-to-tiff-page.ts to utilize wasm-vips for TIFF encoding, replacing previous UTIF implementation.
- Introduced TiffOptions interface in pdf-to-tiff-type.ts for better type management.
- Updated Vite configuration to exclude wasm-vips from dependency optimization.
