axVal2Index doesn't throw error, when there are two identical values by fuzzy=false

[felixcremer]

I am testing the Axis functions and I found, that axVal2Index only throws an error, when it finds a fuzzy match for multiple objects, and not when it finds a perfect match for multiple objects. I am not sure, how problematic it is, but I find it odd.

julia>     multiplevalax = CategoricalAxis("MultVal", ["One", "Two", "One"])
MultVal             Axis with 3 elements: One Two One 

julia> YAXArrays.Cubes.Axes.axVal2Index(multiplevalax, "One", fuzzy=true)
1

julia> YAXArrays.Cubes.Axes.axVal2Index(multiplevalax, "one", fuzzy=true)
ERROR: Could not find unique value of one in MultVal             Axis with 3 elements: One Two One
