Commits on May 12, 2020

  1. Add optimisations 

    - Use NUMEQUALVERIFY for the final function in a contract
- Only drop final OP_VERIFY if remaining stack < 5
- Calculate byte size for OP_RETURN output HexLiterals
  so this does not need to be done by the script
- Update fixtures

  2. Add start of OperationSimulation 

    - UnaryOp and BinaryOp can now be simulated if all operands are literals
- bitcoin-ts is used for this simulation so it's executed as it would be in practice

  12. Allow Blocks to be used as Statements 

    - This is a prerequisite for simplification of (among others) if-statements
- Make list of statements required (it was already de facto so)
- [Code generation] Move scope depth tracking and scope cleanup
  to BlockNode rather than BranchNode

  14. Finalise OperationSimulations 

    - Add applySplitAndIndex
