Input task needs to be simplified: all formats give the same data

• All data consists of several channels with random names.
• Every channel inside each file will have a URL.
• Every channel has either the shape (Nchan,) or the shape (..., Nchan)

HDF5, DAT, CSV, XMU: it is all the same, except for the URLs and the data reading.

Essentially you have energy, mu, i0, i1, i2, ... and each has shape[-1]==Nchan.

Note that the energy could have shape (Nfiles, Nchan) for .dat files but est only allows selecting 1 .dat file.
