it's functional.  was a bit of a pain to recognise N(xyz) and other patterns
but it's functional.

am now running with this

#!/bin/sh -xe

pypowersim -g audio/mp3/mp3_0.gpr \
        -s common.spr \
        -p 0x20000000 \
        -l data/audio/mp3/mp3_0_data/buf${1}:0x600000 \
        -l data/audio/mp3/mp3_0_data/win0:0x700000 \
        -d ${2}:0x900000:128 \
        -i audio/mp3/mp3_0_apply_window_float_basicsv.bin
cmp ${2} data/audio/mp3/mp3_0_data/samples${1}

and have run into an FP overflow which is not supposed to happen
so will investigate further.
