Move iex-ruby-client out of dblock

[dblock]

Today I got an email from IEX that said it's quadrupling their yearly subscription price, and their entry level paid plan is now $100 a month, so they basically 10x-ed their price. I've been a customer for 5 years. This is way too steep for a small project like https://github.com/dblock/slack-market which is why I wrote iex-ruby-client.

I will not be (co)maintaining this project moving forward. One of the maintainers should step up if interested and help move this project to a new GitHub org, I'll gladly assist with that.

Thanks for the open update. I've enjoyed working with you dblock and giving back to the OSS community. However, short of IEX sponsoring the gem's continued development, I cannot take this on either.
