ffs: Unable to store string to Lotus testnet using PowerGate FFS

Please see the description in this PR ltfschoen/ethquad#7, which includes screenshots, and a list of issues I've encountered, and the list of steps you could follow to replicate the issues.

Hi @ltfschoen. You issue PR mentions "local testnet". I assume that is our localnet docker compose setup? Please see the localnet docs towards the top where it talks about BIGSECTORS and acceptable file sizes to store in Powergate cold storage.

https://docs.textile.io/powergate/localnet/

Not using --bigsectors will limit you to storing files of around 700 bytes and deals will complete in 30-60 seconds. Using --bigsectors will allow you to store files anywhere from 1Mb to 400Mb, but deals will complete in 3-4 minutes. Be sure to choose the value that makes sense for your development scenario.

So whether or not you use big sectors, a cid string is too small. There is also be minimum file size requirements in Filecoin test net and main net.

Pretty sure that is causing your problem. Feel free to open this back up if not.

Thanks I'll try that out. Yes, I'm trying to get it to work on the localnet first https://github.com/textileio/powergate/blob/master/docker/docker-compose-localnet.yaml
