Introduce deepmemory as a replacement for materialize

[mtfishman]

Introduce deepmemory as a replacement for materialize, which reaches down into nested date structures with a system similar to Adapt.jl and replaces serialized arrays with the equivalent in-memory array. Also changes memory to retain some wrappers (similar to deepmemory), but in certain cases like permutedims and broadcasting it materializes the wrapper.
