websocket based api consumer for the bitfinex cryptocurrency exchange

recommended go version: 1.10

required environment variables:

• DB (e.g. postgres)

During prototyping we don't work with binary releases. Just create a binary using

    env GOOS=linux GOARCH=amd64 go build main.go

rename the binary to consumer.bin (for reasons of automatic deployment)
