block genesis finish parsing / printing

Finish parsing of genesis blocks (body), and oretty printing of block

[ghost]

are you open to using a library for the pretty printing, such as https://docs.rs/pretty/0.4.0/pretty/ ?

[ghost]

i guess the answer depends on whether it has dependencies which cannot easily be used in the wasm target.. the pretty library above depends on tempfile but it only uses it for a benchmark.. I'm not sure whether means we cannot use it or not.. i'll assume we cannot for now and see how simple i can make the generic prettyprinter

Ok, so there's a generic prettyprinter now. Next steps:

• bigger todos
  • parse genesis blocks (see how blockchain::normal::Block is parsed)
  • implement Pretty for genesis blocks (use same approach as blockchain::normal::Block implementations)
• smaller todos
  • add color to previous_hash (field of BlockHeader)
  • add color to block_signature (field of Consensus)
  • extend the AST to allow Val::List<Vec<Value>>, use it for lists like transactions and the long list in genesisblocks
