yaml API changed

[erwanp]

Hello, excavating this project, I found a problem with the upstream API to parse yaml file :

 File "C:\Users\erwan\anaconda3\envs\bloc\Lib\site-packages\ctwrap\parser.py", line 261, in from_yaml
    out = yaml.load(yml, Loader=yaml.SafeLoader)
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "C:\Users\erwan\anaconda3\envs\bloc\Lib\site-packages\ruamel\yaml\main.py", line 1085, in load
    error_deprecation('load', 'load', arg=_error_dep_arg, comment=_error_dep_comment)
  File "C:\Users\erwan\anaconda3\envs\bloc\Lib\site-packages\ruamel\yaml\main.py", line 1039, in error_deprecation
    raise AttributeError(s, name=None)
AttributeError:
"load()" has been removed, use

  yaml = YAML(typ='rt')
  yaml.load(...)

and register any classes that you use, or check the tag attribute on the loaded data,
instead of file "C:\Users\erwan\anaconda3\envs\bloc\Lib\site-packages\ctwrap\parser.py", line 261

            out = yaml.load(yml, Loader=yaml.SafeLoader)

Fix coming
