Timer Interrupt clear is incorrect

[jonathanpallant]

This code in timer.rs:

pub fn unlisten(&mut self, event: Event) {
    match event {
        Event::TimeOut => {
            // Enable update event interrupt
            self.tim.dier.write(|w| w.uie().clear_bit());
        }
    }
}

should be

pub fn unlisten(&mut self, event: Event) {
    match event {
        Event::TimeOut => {
            // Enable update event interrupt
            self.tim.dier.modify(|_r, w| w.uie().clear_bit());
        }
    }
}

The write call will disable all the interrupts, not just that specified one.
