Output more friendly exception messages in case of serialization failure, like what property failed to serialize according to the schema

[sergiutugulschi]

When I try to serialize an object that has a not null string property in avro schema but I set is as null in code I'm getting System.ArgumentNullException: String reference not set to an instance of a String. (Parameter 's')
at System.Text.Encoding.GetBytes(String s)
at Transaction serializer(Closure , TransactionAvro )
at Chr.Avro.Serialization.BinarySerializer`1.Serialize(T value)

Not clear at what property it failed, it will be better to have an exception like Serialization failed, expected property {nameOfTheProperty} to be not null but was null. Or exepected property type to be string but was int, etc.

This situation is somewhat improved at serde build time with 39fa633, but improving runtime exceptions like the one shown above will need some additional investigation to implement without impacting performance.
