/**
 * Wraps an `mssql` ConnectionPool (or a Request) to intercept query execution timing.
 *
 * Works by monkey-patching the `request()` method on the pool so that every
 * `Request.query()` / `Request.execute()` call is measured automatically.
 *
 * Alternatively, you can pass an `mssql.Request` instance directly and only
 * that single request will be instrumented.
 *
 * @example
 * ```ts
 * import sql from 'mssql';
 * import SqlSlow from 'sql-slow';
 *
 * const pool = await sql.connect(connectionString);
 * const monitor = SqlSlow.create(null, { alert: '>500ms' });
 * attachMssqlAdapter(pool, monitor.monitor);
 * ```
 *
 * @param conn     An `mssql` ConnectionPool or Request instance
 * @param monitor  The SqlSlowMonitor to forward events to
