Dev ship data

[kok-foong]

Requested by you-know-who to display more ship data that are relevant to regulations.

Main addition: 1) New derivation that is derived from ship and derived using ShipDataAgent. 2) ShipDataAgent

• supposed to calculate new quantities based on some available ship data. At the moment just adds static values for energy efficiency, specific fuel consumption, carbon intensity index, specific CO2 emission
• Design intention is to hopefully have some simple models to calculate additional quantities from readily available data
• Currently limited by the amount of data available, need information that ship owners don't typically reveal, such as power rate, type of fuel used, specific fuel consumption

Checked locally that it works for static JSON and CSV ship data. Can be merged once the comments are addressed.
