C++ interface for providing columns by name

[alexander-held]

Similarly to the possibility to hand over dictionaries that specify column names in the Python API, it would be useful to have support for maps or a compile-time solution that allows doing this in C++. This helps mitigate issues where columns are handed over in the wrong order.

A partial implementation was discussed also in #8 (comment)

Somewhat surprising, the python highlevel correction does not accept keyword arguments, even though it would be a trivial addition:

correctionlib/src/correctionlib/highlevel.py

Lines 88 to 90 in 35039db

	def evaluate(
	self, *args: Union["numpy.ndarray[Any, Any]", str, int, float]
	) -> Union[float, "numpy.ndarray[Any, numpy.dtype[numpy.float64]]"]:

That's not a thing, right? As per Nick's message above
