Training ConformerCTC suitable for online inference
### Feature request

Provide a mechanism (or docs if already possible) for training a Conformer model with CTC loss function, such that when inferring live using blocked buffered data, you get the same output as if passing the whole data in one go. Also, discuss if this is resilient to sample offsets.

### Motivation

I would like to use a Conformer model trained with CTC loss live using buffered data coming of a sensor.

### Your contribution

Maybe if i had guidance
