In order to get tracebacks that work with AOT, we need to be able to dump sourcemaps and use them again later. Putting them in a separate file is the obvious solution but that is not useful when compiling single-file executables. In addition, if the standalone executable does not contain the fennel module itself, there's no way to run fennel.traceback.

One potential solution is to extract fennel.traceback similarly to fennel.view and allow it to be included as a standalone module without bringing the entire compiler along with it.

This module could also be used as a storage location for sourcemap data. TODO: how does this actually get emitted in the Lua output in a way it can be used? Putting it at the start throws off the line numbers; putting it at he end means it won't be visible until after the code has run.
