Release 2.0.0

• Uses NumPy to accelerate parsing and calculation.
• Breaking change: returns data as NumPy arrays
• Includes a fix to read CUBE files written by CubeWriter 4.8 that sometimes come with incorrect checksums.
• Includes a bugfix, that switches the paramaters of convert_to_inclusive and convert_to_exclusive in the value
  and mean function of MetricValues, so that the names and the functions match.
  The new and also correct signatures are now:
  mean(self, cnode: CNode, convert_to_exclusive: bool = False, convert_to_inclusive: bool = False)
value(self, cnode: CNode, convert_to_exclusive: bool = False, convert_to_inclusive: bool = False)
