Data items serialization

[asmie]

Block/Header and State data serialization.

It may use the serialization codec from Appendix C.

The question is: can it be SCALE?

@asmie Appendix C of the Graypaper appears to discuss the SCALE codec.

Several points lead me to this conclusion:

• The definition of E (epsilon) in the index refers to "The scale encode function. Superscripted −1 to denote the inverse. See appendix C." (page 56).
• Safrole test vectors are provided in both JSON and SCALE formats.
• The rules for the JAM prize give as example the SCALE codec when mentioning the allowance of third-party libraries.

Due to possible misunderstanding the integer serialization task need to be reopened.

According to this message the serialization of integer differ slightly from Scale

SCALE codec was thrown from the GP. We need to get back to this task and do the right codec.
