tcga-vcf-reheader.py no longer works with the latest version of pyyaml (version 6.0)

[pwaltman]

the specific error is:
File "/opt/tcga-vcf-reheader.py", line 13, in <module> import yaml File "/usr/local/lib/python2.7/dist-packages/yaml/__init__.py", line 362 class YAMLObject(metaclass=YAMLObjectMetaclass):

The quick-and-dirty solution is for the user to use the previous version of pyyaml, e.g. pip install pyyaml==5.4.1, which still works, however, are there any plans on updating these tools to work with more recent versions of the packages it uses? Since this edittor is screwing up the formatting, here's the same error text, but without the code tag.
