3.0.0

[azazellochg]

• Update extra labels list for particles:

PARTICLE_EXTRA_LABELS = [
    'rlnCtfBfactor',
    'rlnCtfScalefactor',
    'rlnPhaseShift',
    'rlnGroupName',
    'rlnGroupNumber',
    'rlnRandomSubset'
]

• set PARTICLE_EXTRA_LABELS inside ClassesLoader and refine3d _updateParticle
• Fill random subset by default. Is there any use case when we do NOT want it?
• Autoscale input vol refs with relion not xmipp
• Add volume resize protocol with a test
• Fix add CTF grouping to 3d init protocol #253, rlnMicrographOriginalPixelSize has to be updated #256, add 3.1.1 tgz #258, polishing returns wrong pixel size #269
• Add missing ProtRelionExportParticles to protocol tree
• Fix default values for missing ctf attrs
• Use abs paths when creating symlinks - important for making scratch work
• Add warning about dm4 gain flip by xmipp
• Fix error in multi-body protocol
• Optimize imports
