Can I pass cont_fut="concat" to prices_to_signals?
I can create continuous futures by passing cont_fut="concat" to functions like get_prices or download_history_file, but not sure if that is possible to prices passed to Moonshot (e.g. prices_to_signals).
Without cont_fut="concat" , get_contract_nums_reindexed_like returns "ValueError: Index contains duplicate entries, cannot reshape".
If there are other ways to fix the above ValueError, that will do too.
