Agree that Pipette will be a good AdditionDeviceType option to have.

Enum option has been added into bdeadman/ord-schema:schema_added_enums but I will have a think about other addition device options that synthesis chemists may need before making the pull request. The immediate gap that comes to mind is pump(s) but I know these are also defined under FlowConditions so there may be good reasons not to allow a pump enum under input AdditionDeviceType.

Issue #607 can also be addressed at the same time.

Pull request #718 will add pipette, and positive displacement pipette as options.
