fix: Price which is set to 0 for CartItem / AdditionalCost are not …

…ignored (#19)

### Problem
Open API Generator sets `DataMember` attribute's `EmitDefaultValue` per default to `false`.

Unfortunately for some of our data models, it means that the emitted JSON for decimal values of `0` are ignored.

### Solution
There's no nice way to address the problem gracefully using a configuration value for the Open API Generator, so currently we manually override the setting for those models.

Currently supported:
 - `CartItem`'s `Price` property
 - `AdditionalCost`'s `Price` property

### Commit Summary
* Force emitting default value of CartItem price (0-value decimal)
* Also force emitting of zero values for additional costs's price
* Bump version to 4.0.2
