Add TypeSafety to Entity.toObject()

[SpencerKaiser]

Is your feature request related to a problem? Please describe.
.toObject does not have solid TypeSafety for the args or on the return type

Describe the solution you'd like
Refactor the method to have a signature similar to the following:

T.toObject(ignoreFields: [keyof T][]) => Omit<EntityDTO<T>, typeof ignoreFields>

I believe it's possible to infer the type of ignoreFields, but maybe not... if not, maybe a generic argument?

Looks like this does the job just fine, given we don't support dot paths in there, it can be really simple:

toObject<K extends EntityKey<T>>(ignoreFields?: K[]): Omit<EntityDTO<T>, K>;

The EntityKey type removes function properties and symbols from keys.
