new image and hdf5 support
First attempt of using imageio for image support and h5py for HDF5 support.
This is still a working in progress. I hope to have definite MR by tomorrow.
closes #23 (closed)
PS: I'll open an issue on imageio to get some issues solved as soon as possible

- 76ba2dbd - Deprecation move. ported image and new hdf5 support
There you go.
In this MR I rewired
bob.io.baseto use imageio as image support and h5py as hdf5 support. Follow bellow what was done in this package.- Removed all the C++ code. bob wise, this package depends on bob.extension only
- Kept the
bob.io.base.loadandbob.io.base.saveAPI; so all the code that depends on this API will not break - Used imageio to read/write all types of image format.
- Used h5py to read/write numpy arrays
- Dropped the support to
HD5File. All complex hdf5 files used upstream should be ported to h5py. - Moved some functionalities from
bob.io.imageto this package (to_bob, to_matplotlib, opencvbgr_to_bob, bob_to_bgropencv)
I'm already testing this on my facerec baselines to see if has some impact on error rates.
This MR is big and will allow us to deprecate

I've just benchmarked this MR against several FR experiments.
I'm posting here the most extreme one: iresnet100 on IJB-C_test1.
Differences are slight as you can see in the table below and in the plot attached.
I think we are good to go with this MR.
