# add :preamble option to compiler

## Description

1) reamble 's value will be a vector of paths
2) the compiled output is prepended with the contents of the files at those paths
3) the generated source map points to the correct/adjusted line numbers

Additionally, when compiling for the :nodejs target the preamble contents will default to the hashbang we currently write in that situation.
