v0.2.0

It supports full conversion between French and YDS grades, by implementing the YDS-to-French conversion path.

Features

• pyclimb.convert now supports conversion from YDS grades to the French grading system.

• pyclimb.convert has a new required argument called grade_system that refers to the grade system in which grade belongs. This contextual information is necessary in order to be able to map between multiple grading systems.

• GradeConversionError exception now includes the user-defined param that led to the raising.

• GradeConversionError exception chaining is now explicitly suppressed, for simplicity. For example:
  before:

    >>> pyclimb.convert(grade='9c', grade_system='French', to='foo')
    
    Traceback (most recent call last):
      File "/workspaces/pyclimb/pyclimb/converter.py", line 33, in convert
        output_grading = GradingSystem(to)
      File "/opt/python/3.8.12/lib/python3.8/enum.py", line 339, in __call__
        return cls.__new__(cls, value)
      File "/opt/python/3.8.12/lib/python3.8/enum.py", line 663, in __new__
        raise ve_exc
    ValueError: 'foo' is not a valid GradingSystem
    
    During handling of the above exception, another exception occurred:
    
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/workspaces/pyclimb/pyclimb/converter.py", line 36, in convert
        raise exceptions.GradeConversionError(
    pyclimb.exceptions.GradeConversionError: Grade could not be converted: foo is not a recognized grading system.
  

  now:

    >>> pyclimb.convert(grade='9c', grade_system='French', to='foo')
    
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    NameError: name 'pyclimb' is not defined
    >>> import pyclimb
    >>> pyclimb.convert(grade='9c', grade_system='French', to='foo')
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/workspaces/pyclimb/pyclimb/converter.py", line 36, in convert
        raise exceptions.GradeConversionError(
    pyclimb.exceptions.GradeConversionError: Grade could not be converted: foo is not a recognized grading system.
