Low level support for decoding avro values. This class has two types of funtions. One type of functions support decoding of leaf values (for example, decodeLong and decodeString). These functions have analogs in Encoder.

The other type of functions support decoding of maps and arrays. These functions are arrayStart, startItem, and arrayEnd (and similar functions for maps).
