Draft: Do not merge: Demo

You need:

emturner@test-demo branch of trili/kernel
you can show the test_kernel/src/lib.rs, which has all the non-computation bits stripped out, so is very short
run ./scripts/demo-compile.sh - this should produce demo.wasm demo.hex demo.wat files in the repo root
cat demo.hex and copy output to clipboard

1. switch to tezos - the branch of this MR
2. run dune utop src/lib_scoru_wasm and then the following commands:
3. open Tezos_scoru_wasm.Gather_floppies ;;
4. let bs = Complete_kernel (`Hex "" |> Hex.to_bytes) ;;
5. Data_encoding.Binary.to_string_exn origination_message_encoding bs |> Hex.of_string
6. copy output to clipboard
7. switch to tezt/tests/sc_rollup.ml
8. replace the string in computatation_kernel () with the clipboard contents
9. from terminal run tail -f scoru-node-debug-log.txt
10. from different terminal run ./scoru-test compute
11. You should now see the rollup originated with the demo kernel, and progress made in the logs
