Partial objects or @Lazy

Usually, ObjectBox is superfast and even a bigger numer of unused properties does not matter. For entities containing properties containing alot of data (e.g. large byte arrays, images, etc.), we might offer a convenient solution.

1. Partial objects are classes that can be used almost like entities, but are read-only and are tied to an entity type. Those have only a subset of the properties.

2. @Lazy on individual properties to load expensive properties lazily.

@Lazy advantages:

• avoids another type and thus complexity

Partial objects advantages:

• more memory efficient if there are alot of properties

Happy to get more input on this.
