Scipion-em

- Hot fix: Import volumes annotates the filename in the volume/s

- Hot fix: protocols.conf is packaged now!

users:
- Version compatible with latest released scipion-em-chimera plugin.
developers:
- biopython updated to 1.79
- Using Alphabet from new version of biopython, related tests modified and added.
- DataViewer allow for registration of new sets using: DataViewer.registerConfig(type, configDict).
Useful for tomography sets and avoiding unnecessary inheritance.
- Icon is a png (compatible with future pillow versions)
- weakImport("tifffile") added when registering FileHandlers (bug at installation in github action)

users:
- Subset protocol optimized, specially for small parametric subsets (random or by ids)
- Assign angles protocol optimized.
- Filebrowser: thumbnails info shown always without the need of loading viewers.
- Thumbnails for mrc files (and its flavours) show also headers sampling rate.

developers:
- Plugins discovery takes into account priority packages: pwem, tomo, ..
- FileHandler registration moved to main pwem.__init__.
- Import volumes uses logging
- Import volumes fixed when downloading an EMDB.
- Dataviewer allow registration of other sets. Dataviewer: DataViewer.registerConfig(tomo.objects.SetOfTiltSeriesCoordinates)

- Plugin.guessCudaVersion returns Version("0.0") for cases like this /usr/lib/x86_64-linux-gnu

users:
- New protocol: Mathematical operator.
- Import sequence protocol can now download sequences from GeneBank. In the past only
UniProt was accessible. In general Unitprot does not have information about
proteins not well know AKA "uncharacterized proteins"
- "import particles" protocol accepts cryoSCPARC particles files
- Import coordinates fixed for complex streaming cases.
- Extract particles does not need SetOfMicrographs is "same as coordinates" is used.
- AtomStruct attributes viewer now can plot attributes over the structure sequence

developers:
- Methods to guess the cuda version from a variable that point to a folder in Plugin class:
(Plugin.guessCudaVersion(varname)). Follows links.
- Allow indirect pointers in SetOfClasses.
- Warning added in SetOfCoordinates.setMicrographs when not using an indirect pointer.
- Warning added in SetOfClasses.setImages when not using an indirect pointer.
- data.py test_workflow_mixed.py and uses logger instead of print
