Based on the now defunct project @
https://github.com/waytrade/ib-gateway-docker
Adds a `docker-compose.yml` and necessary gateway and `IBC` config
files to make it possible to spin up a local gateway on localhost:4002
and connect to it without issue using `ib_insync`.
Next up, we'll want to,
- automated the equivalent docker-compose steps using our
`.data._ahab` supervisor system
- probably simplify and roll our own container (likely alpine or nixos
based) which drops uneeded deps (`socat`, vnc) and adds `xdotool`.
- allow for API socket mapping to just be pulled direct from
a user's `brokers.toml` and we'll just pass that direct to `IBC`'s
config.
