Failed to run DrQ+ReDO

Hello there,

I wanted to reproduce the result of DrQ+ReDO on Atari 100k. Although there is a DrQ gin file in the config directory, it couldn't run successfully by simply using this config file: `python -um dopamine.labs.redo.train --base_dir ~/tmp --gin_files dopamine/labs/redo/configs/DrQ_eps_dense.gin`. It produces a series of errors when I was trying to execute it. At first it was
`ValueError: No configurable matching 'get_mask_updater'.`,
and then after I annotated this line in the gin file, there was error in the `_run_one_step` function in the `run_experiment.py` file. There were still errors after I fixed the error in the `_run_one_step` function.
I wonder if I have missed something. I would appreciate it if you can provide some instructions on this. Thanks!
