Generate Debug map + breakpoint set for use in debugging

[localhuman]

For use in debugging with neo-gui-developer or in a future neo-python debugging implementation, we need to generate a debug map that maps each instruction to a line number of a piece of code in each file.

This, together with a set of breakpoints that correspond to the map and instruction can be used to pause/inspect/step over or in general perform normal debugging tasks.

Just a heads up! @Relfos already implemented this in the pre 3.6 version. His code just needs to be ported to the new setup. His implementation can be viewed here:

neo-boa/boa/code/module.py

Line 570 in 06b1bfc

def export_debug(self, output_path):

We now have debug maps!

Anyone have a good idea of how to gather a breakpoint set from various editors? I was looking into the PyCharm IDE and how it stores breakpoints but couldn't determine how that is done.

An easy editor-agnositc solution would be to add a breakpoint() method which can be placed anywhere and would be ignored by the VM but place a breakpoint in the debug map.

This is now implemented.
