Run key combos for resetting data feeds and yield back to caller

NOTE: this is a linux-only hack around!
There are multiple "techs" you can use depending on your infra setup:
- if running ib-gw in a container with a VNC server running the most
performant method is the `'vnc'` option.
- if running ib-gw/tws locally, and you are using `i3` you can use
the ``i3ipc`` lib and ``xdotool`` to send the appropriate click
and key-combos automatically to your local desktop's java X-apps.

TODOs:
- a return type that hopefully determines if the hack was
successful.
- other OS support?
- integration with ``ib-gw`` run in docker + Xorg?
- is it possible to offer a local server that can be accessed by
a client? Would be sure be handy for running native java blobs
that need to be wrangle.
