Implemented DSN Connection Strings Support

This PR introduces support for DSN connection strings to simplify the configuration process. Users can now use a single string to determine the type of connection (`Network` or `Pipe`) and its details.

This PR resolves #28, closes #25, resolves #26, closes #27, closes #31

1. Added a static `createFromDSN` method to the `ClamAV` abstract class. This method parses the provided DSN string and returns an appropriate instance (`Network` or `Pipe`).
2. Updated the `ClamAVTest` unit test to cover the new DSN creation functionality.
3. Updated composer dependencies
4. Applied smaller code, and documentation optimizations
5. Improved code coverage
6. Updated README

Users can now initialize a connection using a DSN string:

```php
$clam = ClamAV::createFromDSN('tcp://localhost:3310');
$version = $clam->version();
```

This approach provides a more flexible and user-friendly way to set up a connection.

The existing unit tests have been updated accordingly.
