Ugly error message when the JSON syntax is not correct

[vargenau]

bug.spdx.json

JSON syntax of file bug.spdx.json is not correct, there is an extra comma at line 32.

pyspdxtools -i bug.spdx.json

results in an ugly error. See below.

Instead, exception json.decoder.JSONDecodeError should be catched.

pyspdxtools -i bug.spdx.json

Thanks for reporting this!
I opened #779 to fix this and similar issues for YAML, XML and RDF-XML.
