Use HFile instead of h5py.File in most places

[GarethCabournDavies]

Use pycbc.io.hdf's HFile class rather than h5py.File directly so that we can make changes to the functionality.

For example checksumming, version information, and anything else we may want

Note that I haven't touched bin/plotting/pycbc_plot_bank_bins, as that is already subclassing h5py.File, though I'm not sure whether the functionality which is there already exists elsewhere

I have also avoided live (due to efficiency worries) and inference, so as not to interfere with the h5py.File wrapper used there
