Run on the browser

**Is your feature request related to a problem? Please describe.**
I would like to be able to run the bundletool command-line tool in a web browser, possibly using WebAssembly. Currently, bundletool is only available as a Java command-line tool and cannot be run directly in a browser.

**Describe the solution you'd like**
I would like a version of bundletool that can be run in a web browser, possibly using WebAssembly. This would allow me to use bundletool directly from a web page without having to install and run it from the command line.

**Describe alternatives you've considered**
The only alternative would be to continue using the bundletool command-line tool and run it outside of the browser.

**Additional context**
