E4x is the correct ID, not E3x, for MOD and XM.
Additionally, updated the coding style for MOD to be more consistent with the
pre-existing code, namely by not using hex for the effect IDs being checked.
Fine print:
- OpenMPT hacks are not implemented here for MOD and XM for random waveform
- Retrigger/Continuous setting is not handled for MOD, XM and S3M
-- For S3M, I can't confirm if the setting even existed:
I'm pretty sure it got cut out of Impulse Tracker.
- Your waveform may sound different here than in the original player
If tremolo and panbrello waveforms are implemented in Furnace, then their
corresponding conversions can be implemented. For now, though, they can't make
the cut since there is no corresponding effect to change those waveforms from
the default setting.
