Improvements

#337 - Add non-explicit default constructor to emitted c++ API (regression)

Zserio v2.4.0

The main goal of this release is to publish the following brand new language features:

• Rules
• Packed arrays

Rules provide a way how to organize semantic restrictions for the schema which cannot be easily defined using constraints.

Packed arrays compress all integer types, enumeration types and bitmask types using delta compression.

Beside of that, Implicit arrays are deprecated in the language from this release.

Furthermore, the release contains the following new features in generated code:

• Types schema info in generated Python code
• New allocation strategy in generated C++ code
• New Zserio array types mapping in generated Java code

#326 - Improve checking of implicit arrays usage
#327 - Check never ending recursion via non-empty array
