timers rework

@burrbull I updated the Cargo.tml to point to this branch. The code compiles and flashes the chip with no problems, however while observing the LED I am noticing different behavior than what's programmed. For instance

loop {
            // On for 10s, off for 30s.
            led.set_high();
            // Use `embedded_hal::DelayMs` trait
            delay.delay_ms(10000_u32);
            led.set_low();
            // or use `fugit` duration units
            delay.delay(30.secs());
        }

If I understood the comments correctly the LED should remain on for 10s and off for 30s, however I am observing the opposite. The LED is on for 30s and off for 10s.

Is this just user error on my part?

It is just how your LED is connected on scheme.
set_high mean set +3.3 V on pin, set_low mean set 0 V.
If your LED is connected inverted, it will light at 0V and will be off at 3.3v
