Check required for normalisation of Fund Data

[Clare2D]

In some cases the weight of isins in a fund exceeds 1 where it should not (ie it should be == 1). This is generally not a major issue and can be avoided by normalising the weight of each isin in the fund by the total weight of the isins in that fund. If not done, it may cause the error to appear that the “fund data introducing error in total value”

In the data cleaning we need to check for this and normalise if necessary.

I assume this is largely related to #368?

Not this one actually.
