CRNN learner in fastai

I was searching for a CRNN learner in fastai, couldn’t find one. Then I got across PyTorch implementation of crnn. But since, I am so in love with fastai, I rewrote it in fastai.

I want my CRNN implementation to be a part of the official fastai library. Is this possible? I understand it might not be up to fastai’s standards, but I am hoping if I can collaborate with fastai to work on it. @jeremy @muellerzr
