The main method of SerializerFinderVisitMethodCall uses huge switch by method name and then each DeductXXXMethodSerializers double-checks if the methodinfo belongs to list of supported method, that list sometimes could be relatively big and we iterating through all items.

We can improve this by having static Dictionary<MethodInfo, delegate> which will contains all serializer deducers by methodInfo. Having single dictionary instead of switch and double-checking methodInfo reduce amount of code required for each method support, reduces risk of wrong copy-pasting and probably more performant.
