Parses the given Live Markdown document and converts it to Elixir
source code.
## Limitations
Note that the resulting script may not compile in some cases, for
example if you define a macro in one cell and import it in another
cell, it works fine in Livebook, because each cell is compiled
separately. However, when running the script it gets compiled as a
whole and consequently doing so doesn't work.
Additionally, branching sections are commented out.
