Re-enable x86 for Android and x86_64 for iOS

[Johennes]

Due to size limits on npmjs.com, we had to disable some x86 for Android and x86_64 for iOS with 54ca156 and 58b948f. Ideally we'd be able to distribute the binaries for these platforms as well.

I couldn't find it documented but the size limit might be around 200mb packed. Without these architectures, the package is around 175mb.

Possible solutions I've thought of so far:

1. Don't include any binaries at all and let consumers build them on their own
2. Host the binaries somewhere else and download them with a package.json script on install

CC @olliiiver since you've contributed some fixes for the x86 builds in the past and might possibly be relying on them.

Hi @Johennes.

Thanks for providing an update to the library.

I think removing x86 for Android is fine since most people are on x86_64 nowadays. I'm not entirely sure about Intel Macs after removing x86_64 for iOS, but looks like the Github workflows are still running.

We could think about having the prebuilds downloaded like node-canvas is doing it:

They use prebuild-install to download binaries from Github:

https://www.npmjs.com/package/prebuild-install

Oh, interesting. So we could attach the binaries to a GitHub release and then fetch them from there, e.g. with a postinstall step. That sounds feasible.
