v3.1.0

The main change in this release is the data_harvester behavior which is now using threads to download data objects/files. This allows to include more data files for the assessment. In detail, F-UJI now is trying to analyse up to 5 files per mime-type (as listed in the metadata).
Some other changes to note:

All: Incorrect handling of some landing pages which cause the evaluator to stop has been fixed.
R1.1: Licenses packed as lists are now unpacked and correctly identified
I3: In some cases scores for I3 are improved due to the inclusion of schema.org/citation as scanned relation property
R1: Incorrect handling of file sizes given or interpreted as strings like 'None', which were accepted as valid content, caused incorrect (too high) scoring of R1, score might be lower but correct now in theses cases.
R1: Improved handling of mime types including e.g. charset info (text/plain; charset=US-ASCII) may result in higher score for R1 (FsF-R1-01MD-3)
R1: Improved parsing of content length byte units may improve the scoring.
F2: Improved handling of RDF graphs containing DC or schema.org terms to describe the content may improve findability and other scores
R1.3: F-UJI now uses threads to download more data objects (up to five files/links per claimed content type) which improves its capability to evaluate data content
