Initial offline process implementation

Implemented the initial offline processing implementation, with
dependency layer building and ordered processing

Processing is still single threaded and unoptimized so it can take some
time to complete, the next step is to move from a single threaded design
to a ThreadPoolExecutor that splits up the buffer into a set number of
chunks for processing
