Detailed Description

SimplifyCTCGreedyDecoder converts v6:CTCGreedyDecoderSeqLen into v0::CTCGreedyDecoder.

       data[N, T, C]    seq_len[N]
              \          /
       CTCGreedyDecoderSeqLen

will be converted to

      data[T, N, C]   seq_mask[T, N]
               \         /
             CTCGreedyDecoder
               /         \
  class_index[N, T]    seq_len[N]

The transformation works only for case when the blank_index input == C-1, where C is the number of classes.
