# parse code listing
# - has problem that in Devpac output the offsets in
#   the code listing part don't take includes into
#   account i.e. they seem wrong
#   
# works by:
# - removing columns that confuse rest command line
# - removing macro etc symbols at zero address
# - removing (optional) ':' from symbol end
# - matching addresses & symbol names and print
#   them in 'nm' order
