Switch to a standalone ARC4 implementation (#1788)

* Switch to a standalone ARC4 implementation This frees us from expecting it being provided by one of the crypto libraries we support, all of which deprecated and/or removed it at this point. Fixes: #1103 Fixes: #1777 * Suppress lgtm warnings about RC4 being weak (we don't care)
