When I try to run in in WASM, the game freezes when I hit a key and I get this in the console:

panicked at 'time not implemented on this platform', library/std/src/sys/wasm/../unsupported/time.rs:13:9

wasm.js:414:9

How to reproduce:

1. Copy the setup from examples/singleplayer.rs
2. Replace the code in check_input with this

use EnumeratedBinding::*;
use EnumeratedMovementBinding::*;

if let Some(vertical) = query.single().axis(&Movement(Vertical)).first() {
    if vertical.press.just_pressed() {
        println!("just pressed");
    }
}

Issues:

1. This code will print "just pressed" more than once when a key for the Vertical axis is pressed.
2. If the key is held down and auto-repeat is enabled in the OS (it's enabled for me in Windows 10) it will print every frame once auto-repeat starts.

I believe that 1. is caused by using a fixed value of 75ms in src/press_state.rs instead of something like deltaTime

// just_pressed
if let Some(instant) = started_pressing_instant {
    instant.elapsed().as_millis() <= 75
} else {
    true
}

but I don't know what would cause 2. (the auto-repeat issue)

Looks like it works just like that - no code changes required.

I did not change the crate's version - that's your job to decide (e.g. - should the macro crate's version change too?)
