Relabeled HCL does not work with test_words.py

Hi,

I create HCLr.fst with the following procedure:

`./utils/mkgraph_lookahead.sh --self-loop-scale 1.0 --remove-oov --compose-graph exp/chain/tdnn1g_sp_bi exp-train/chain/tdnn1g_sp_bi/graph_lookahead`

I use this HCLr with test_words.py, but it does not work because the dinamically created Gr.fst is not relabeled and not fstarcsort. If I manually create a Gr.fst including the relabeing (command below) process and use it with the HCLr.fst, then everything works fine. My question is: how do I create a HCLr.fst that can work with test_word.py?

Thank you!
