New reusable assets + new gamemode (timelimit/out of time) with procedurally generated tracks

[lrq3000]

First, let me thank you very much for the amazing engine you provided and the tutorials.

I have enhanced the game a bit by replacing the assets with reusable ones under permissive licenses or made from scratch, and I added a new "out of time" gamemode with a timelimit to reach the next finish line with procedurally and randomly generated tracks (but the old "fastest lap" gamemode is still available, and also supports randomly generated track).

I also added a few things in the engine such as a rudimentary day-light cycle simply replacing the background with a progressive blending effect.

Also added a turbo, and support for mobile devices (with touch controls).

And the sourcecode is here (same as this PR): https://github.com/lrq3000/javascript-racer

Did you have a zip folder download available for this? Just getting into java so I can make mini games for my visual novel and I'd love to play around with this version some more, It looks really nice and the touch buttons are a neat functionality.

@Smugglerofnoise Yes you can download this whole PR here as a zip :-)

@lrq3000 literally right as I am looking for replacement sprites for the regular javascript racer to make a synthwave version, I find this lol should I still make it?

[lrq3000]

@stewpidtnlvr Yes, why not? Feel free to reuse sourcecode of this repo to speedup your work if you want or restart from scratch to entirely unleash your creativity :-)

@lrq3000 I hate to bother you again, but would you mind telling me how to change one of the billboards? | edit: ok so I did some research. I was wondering if you could tell me how to edit the already-made svg file so I can change a billboard?
