Update to gif 0.13

To the tune of #1826.

Looks like the OOM regression test now fails due to some additional checks added by one of the recent PRs of @kornelski.
Could you maybe offer some advice here please?
Should the test data be altered to pass this new check, or should a different error be expected now?
My hunch is on the former, but I'm not familiar enough with the GIF format to know exactly what to change...

The GIF has lzw code size == 0, but the minimum valid value is 2. You can change the data to this:

    let data = [
        71, 73, 70, 56, 55, 97, 0, 0, 0, 0, 0, 0, 0, 44, 255, 255, 219, 255, 172, 199, 199, 255,
        216, 255, 255, 0, 0, 48, 230, 2, 195, 195, 195, 195, 255, 239, 0,
    ];

and you will get the Limit error due to default memory limit of 50MB.

Awesome, thank you so much!
