Fixes #104.

Usage:

python python/scannerpy/python_master.py  # start running python master
python tests/test_realtime.py  # start test client

API:

input = db.ops.MemoryInput()
output = db.ops.MemoryOutput(columns=[test_out])
# ...
input.push(frame.tobytes())
out_frame = output.pull()
# ...
input.close()

Known issue:
The client does not completely shut down after finishes. Might need to kill -9 the process manually for now. I'll try to fix it in a few days.
