Consider renaming main library file for consistency

[Aqudi]

Hey there! 👋

The Dart document (https://dart.dev/guides/libraries/create-library-packages) recommends that the main library file for a package should be named lib/<package-name>.dart. However, the current entry point file for the lottie-thorvg package is named lottiel.dart, which deviates from the recommended naming convention.

For consistency with the guidelines and better discoverability, it might be worth considering renaming the lottiel.dart file to lottie-thorvg.dart.

Thank you!

@Aqudi Thanks for reaching out to the project.

The purpose of the naming was to align the import statement with lottie-flutter as much as possible.

However, I have overlooked the proper package standard. I fully agree with the guidelines and will ensure that this is corrected in next release. The import statement will be import 'package:lottie_thorvg/lottie_thorvg.dart';

Thank you.
