Feature/merge django simba

[PaulScheerRLI]

Merge of various changes made to simba which were necessary for a django implementation. Major feature:

• Introduction of a datacontainer which allows easy replacement of data, and creating scenarios from various data sources.
• Improvements to tests since no file manipulation is necessary
• schedule.from_csv has been removed for schedule.from_datacontainer
• Consumption object is now an attribute of a schedule instead of Trip class, which limited calculation of multiple schedule instances
• Consumption uses vehicle_types from schedule instead of keeping its own reference. This allows for easy changing of schedule vehicle types and consumption calculation

Minor feature:

• Refactoring of some functions
• Introduction of new modes
• Accessibility of SpiceEV greedy simulation
• arguments are not mutated anymore, e.g. deleted or changed in their type
• argument files have the suffix _path
• nd_interpolation failed for duplicate lookup values. this has been fixed
