Hiperspace.Heap

The Heap driver provides the simplest hiperspace, storing objects in the managed process heap, it exists for testing purposes, but also for benchmark performance of other drivers.
The Heap driver uses more memory, and is slower than the Rocks driver.

## Overview
     This Version is a major refactor, taking into consideration lessons learned from implementing hyperspace with blazer web assembly.  It was hoped that .NET 9 would include greater compatibility with runtime type creation (used by protobuf-net for serialisation classes) or that protobuf-net "Ahead of time" (AOT) code generation would be included, but switching to direct protobuf serialization has the additional benefit of simplify usage with {Android, iOS, [Unity](https://unity.com/), zOS, [Meadow](https://www.wildernesslabs.co/)}. **Hiperspace** is the only domain-oriented object mapping technology that can be deployed into these environments, providing transparent sharing of elements between edge devices and server context.

     The companion change to [HiLang](HiLang) includes the generation of serialization code for domain models.

     ### Security enhancement
     Previously the predicates provided to **Horizon**  filters look an instance of an element and return true if it was within the horizon of the subspace.  This has been expanded to allow three types of Horizon Filter
     * `new Horizon<Element_Type> ( element => element.Valid == true)'  a horizon predicate with the element only
     * `new Horizon<Element_Type> ( (element, read) => element.Valid == true || read)'  a horizon predicate with a flag to indicate a read operation
     * `new Horizon<Element_Type> ( (element, context, read) => element.Valid == true || read)'  a horizon predicate with a context parameter and a flag to indicate a read operation
     * `new Horizon<Element_Type> ( (element, context, user, read) => element.Valid == true || user?.IsInRole("BULK"))'  a horizon predicate with a context parameter, user IPrinciple and a flag to indicate a read operation

     Subspace has three labels added to support enhanced security

     | Label name  | Description |
     | ------------- | ------------- |
     | Context        | Context that the space was opened with e.g. "Front Office", "Risk", "Settlement" |
     | User           | an optional `IPrincipal` for access control |
     | Remote     | Was the subspace opened remotely, and security/validation need to be re-applied on the server |


     ### Protobuf-net
     [protobuf-net](protobuf-net) dependency for all .NET assemblies have been changed to [protobuf-net.Core](protobuf-net.Core) which does not include dynamic generation of serialization/deserialization code.

     ### Web applications

     Web applications can take advantage of the HiperSpace shared between the web-client (or desktop applications) and the server session for the user with full lazy loading as required.

     Hiperspace elements are transferred using [gRPC-Web](https://github.com/grpc/grpc-web)  for web-clients {browser, Android, iOS, [Unity](https://unity.com/)}  and [gRPC](https://grpc.io/) for desktop applications.
     gRPC-Web packets are exchanged space efficient binary messages without JSON text conversion
