Blurhash-avif

Fix issue for batch generation library linking

**New Features:**

* `batch_generate_blurhash_from_avif`: Generates BlurHash strings for all AVIF images in a given directory.
* `batch_generate_png_data_url_from_avif`: Generates base64-encoded PNG data URLs for all AVIF images in a given directory.
* `batch_generate_blurhash_and_data_url_from_avif`: Generates both BlurHash strings and PNG data URLs for all AVIF images in a given directory.


**Upgrade Notes:**

To take advantage of these new features, simply update your project to use the latest version of our library. No breaking changes have been introduced in this release, so you can safely upgrade without worrying about compatibility issues.

**Example Use Cases:**

* Generate BlurHash strings for all AVIF images in a directory: `batch_generate_blurhash_from_avif("/path/to/images")`
* Generate PNG data URLs for all AVIF images in a directory: `batch_generate_png_data_url_from_avif("/path/to/images")`
* Generate both BlurHash strings and PNG data URLs for all AVIF images in a directory: `batch_generate_blurhash_and_data_url_from_avif("/path/to/images")`

We hope this release helps you streamline your workflow and improves your overall experience working with AVIF images. As always, we welcome your feedback and look forward to hearing about your use cases!

fixed error for mypy caused by src dir

This release adds support for [mypy](https://mypy.readthedocs.io/en/stable/), a popular static type checker for Python.

**What's new:**

* Added `py.typed` file to indicate that the package contains type annotations
* Updated `setup.py` to include `py.typed` file and enable mypy support
* Verified compatibility with mypy 0.971 and later

**Why is this important?**

By adding mypy support, we're making it easier for developers to catch type-related errors and improve the overall quality of their code. This is especially important for libraries like blurhash-avif, which are used in a wide range of applications.

**Upgrade now:**

To take advantage of these improvements, simply update your `blurhash-avif` installation to version 0.4.0 using pip:
bash
pip install --upgrade blurhash-avif

We hope this release helps you build more robust and maintainable applications with blurhash-avif!
