Add support for continue and break statements

[nielstron]

#297 introduced the option to implement continue and break statements. This did not exist in hebi before since it did not support loops.

One possible implementation is to keep track of a respective call required to return to the closest loop beginning or end directly (i.e. call adjusted_next or while/for)
