/**
 * A template class that can be used to create new SenMLPack types that store a base-value and/or base-sum 
 * with a basic data type (no structs or classes).
 * When you create a new class, you should always implement the following functions in order
 * for the new class to operate correctly: fieldsToJson() and fieldsToCbor(). These functions are responsible
 * for rendering both base-value and base-sum. This class does not implement any rendering.
 * See previous implementations such as SenMLIntPack for inspiration.
