bc7bc29740 Added HDF5 file to demonstrate dynamically plotting a subset of a very large dataset
* Loads only data that is currently visible
 * Downsamples to avoid plotting too many samples
 * Loads data in chunks to limit memory usage during downsampling

3a27997014 Plotting performance improvements:
- AxisItem shows fewer tick levels in some cases.
  - Lots of boundingRect and dataBounds caching
    (improves ViewBox auto-range performance, especially with multiple plots)
  - GraphicsScene avoids testing for hover intersections with non-hoverable items
    (much less slowdown when moving mouse over plots)

Improved performance for remote plotting:
  - reduced cost of transferring arrays between processes (pickle is too slow)
  - avoid unnecessary synchronous calls

Added RemoteSpeedTest example
