Unable to generate ISA-Tab files for a study and associated assays

[dkstayko]

Hello,

Upon executing the command -
isatab.dump(investigation, out_dir)
only 'i_investigation.txt' is generated, and corresponding study or assay files are missing.

On the other hand, a json file containing all investigation, study and assays data is generated successfully via -
with open(os.path.join(out_dir, "isa.json"), "w") as out_file:
json.dump(
investigation,
out_file,
cls=ISAJSONEncoder,
sort_keys=True,
indent=4,
separators=(',', ': '))

I am using isatools 0.14.2

Thank you for your support in advance.
