correct axes for hdf5

[julianhoersch]

This PR fixes #45 I made some manual changes in the code to adapt the content of the hdf5 file to the output that is expected. This is probably not very flexible when it comes to other hdf5 files, but works for the _b4_1_master. The axis description should be correct again:

loop_
  _axis.id
  _axis.type
  _axis.equipment
  _axis.depends_on
  _axis.vector[1]
  _axis.vector[2]
  _axis.vector[3]
  _axis.offset[1]
  _axis.offset[2]
  _axis.offset[3]
