The commented line does not work because `.delay` and `start` want to own `syst` (`ctx.core.SYST`). But I want to use a display which requires a `&mut Delay`
```rust        
let systick_mono_token = rtic_monotonics::create_systick_token!();
//let mut delay = syst.delay(&clocks);
Systick::start(syst, SYSFREQ, systick_mono_token);
```
How do I get a delay for this function: https://docs.rs/st7735-lcd/0.10.0/st7735_lcd/struct.ST7735.html#method.init ?
