Includes a new simulator type, and integration for host simulators to add
memory devices. Currently only implemented for gem5.

For now the devmem command comes in handy, but probably generally good to have.

I basically did the following:
`mkdir experiments/simbricks/orchestration`
`mv experiments/simbricks/* experiments/simbricks/orchestration/`

Additionally, imports and paths had to be adjusted.

otherwise we don't receive CTRL+C in orchestration framework

fixes isort's wonky detection of first- and third-party for modules located in experiments/pyexps import modules from experiments/simbricks
