Unzip files with a different extension(like Telegram's tgs)

[Fra078]

Is your feature request related to a problem? Please describe.
It's not possible to force lottie to read a zipped file with a different extension. I'm developing a telegram client, but telegram stickers are lottie files with images zipped into a .tgs file.

Describe the solution you'd like
I think that on Lottie Compose should be in the class LottieCompositionSpec.File a boolean argument that when is true will force lottie to ignore extension and try to unzip anyway (Throwing an error if the file is not a zip)

Describe alternatives you've considered
Add tgs as file format supported because Telegram is open source, so a lot of developers can have this issue

Adding some additional context here:

1. lottie-android should be able to pick up a zip file regardless of the file extension, as it relies on the header for identification (if it's coming from assets/raw)
2. tgs is not a zip file, it's actually gzip which is quite different. gzip is not (afaik) natively supported on java/android and will likely require additional dependencies
