Struct Waveform 

pub struct Waveform {
    pub shape: u8,
    pub no_retrigger: bool,
}

Vibrato / tremolo waveform selector for E4x / E7x.

Per Protracker-v1.1B-mod.txt:

• low bits 0..=2 pick the shape (0 sine, 1 ramp-down, 2 square, 3 random — random is ignored in PT).
• bit 2 (value 4/5/6/7) disables retrigger on new notes.

Fields

shape: u8

0 = sine, 1 = ramp-down, 2 = square, 3 = random (treated as sine).

no_retrigger: bool

If false, position is reset to 0 on every new note (default).
