Why is ConvertToString not consistently used in Liquid templates?

[IanKemp]

https://github.com/RicoSuter/NSwag/blob/master/src/NSwag.CodeGeneration.CSharp/Templates/Client.Class.ConvertToString.liquid does not take into account the ParameterDateTimeFormat and ParameterDateFormat options, meaning that if you use this function in another template on a date-(time) field, you end up with an incorrectly formatted string.

Looking at other templates, e.g. PathParameter, it actually seems there is special-casing the handling of dates and arrays and avoidance of ConvertString.

Why not just pass all handling through ConvertString and put all the special-casing in there, instead of having some of it there and some of it in other templates?
