Returns an array ("buffer") of truly random 32bit integers, from `/dev/urandom` source.

If you use `%` (remainder operator) to downscale the range, the output will be biased: https://stackoverflow.com/a/10984975

"Access to all files" permission is unnecessary, as it uses AM's own private cache. The filename is the flow's local ID, reducing the chance of collisions.

Executing `xxd` command would remove the need for a temporary file, but it's unavailable on Android < 7. `mktemp` requires Android >= 6.

Executing `head` cmd would improve performance because of its adaptive block-size. But `dd` is available on all Android versions, unlike `head` (Android >= 6).
