Is process type required for Process Tracker?

[OpenDataAlex]

Need to give a think on the process type parameter and it being required on initialization. Originally intended because processes could be created at runtime, but if a process is being created ahead of time and with the rest of it's metadata (i.e. sources/targets/dependencies) then is it really required?

I'm planning to switch process_type to an optional parameter. If provided, it will associate to the process. If not, the process' type will be returned from the data store.
