Serialize reader state

Description (last modified by crueden-x)

Some formats take a long time to parse. Often the reader implementations could stand to be optimized further, but some cases may simply require searching through a large amount of binary data to find planar offsets and other important metadata.

Ideally, Bio-Formats would be able to parse each file once (i.e., initFile()), and then optionally cache the results to a format-specific data object, which is serializable to (e.g.) disk. It could then later be retrieved and used to quickly reinitialize the reader with respect to that same file.
