Sergey Biryukov aa22aba0ba Upgrade/Install: Update sodium_compat to v1.18.0.
The latest version of sodium_compat includes some improvements, as well as a new feature which will also be included in PHP 8.2.

* Fixed issues with the PHP autoloader:
 * [https://github.com/paragonie/sodium_compat/pull/145 #145]: For WordPress, this ensures when Ed25519 is included, so too is the class it inherits from.
 * [https://github.com/paragonie/sodium_compat/issues/148 #148], [https://github.com/paragonie/sodium_compat/issues/149 #149]: For PHP 7.4+ with opcache preloading, this ensures the include guards don't fail.
* [https://github.com/paragonie/sodium_compat/pull/144 #144]: Added `sodium_crypto_stream_xchacha20_xor_ic()`
 * See [https://github.com/php/php-src/pull/8276 pull request for php-src] (merged in PHP 8.2)
 * For motivation: [https://github.com/paragonie/halite/issues/178 paragonie/halite#178]
