The picture text recognition library does not provide a non-gms version, please provide a non-gms version，More than a billion people in China need it very much.

I have checked all Google's ml-kit libraries, only the picture and text recognition library does not provide a non-gms version, and other libraries need gms, which is really unfriendly to millions of developers and more than a billion users in China, and these developers and users also need this library, so please provide a non-gms version, because Chinese users' mobile phones basically cannot use gms.

The issue names no source files, tests, or entry points. Start by reviewing the Android codelab structure and how picture text recognition depends on Google Mobile Services, then determine whether a non-GMS implementation is feasible. The issue does not define the supported alternative or a concrete completion criterion.
