Motivation and Resolution
Fix #588
Usage related changes
Because of cairo0 back compatibility, we left formatting to be compressed program in response class, so it needs to be decompressed for declare and also typecast to legacy.

An example of redeclare cairo0 without a helper will be:
Redeclare cairo0 contract helper:
contractClassResponseToLegacyCompiledContract();
Example Cairo0 redeclare:
