Create a CompressedWorkspace2D and benchmark

Description

create a new workspace type that is similar to ManagedWorkspace2D in that is uses a data store and buffers in a most recently used list. However the back end data store will not be a file, it will be a memory block containing the x, y and e vectors compressed using the zlib library (we already link to this somewhere).

Suggested steps:

  1. in a test see what the compression rates are for sample workspace data. Investigate the compression/decompression rates.
  2. Implement as a new workspace
  3. Benchmark the characteristics f this workspace type against Workspace2D and ManagedWorkspace2D
  4. Once we understand where it should fit integrate the use of this into the WorkspaceFactory and MemoryManager.
