/**
 * Given a Type Guard, returns a Type Guard that does exactly the same but logs the `guard`, `value` before calling guard(value). Logs result after.
 * Equivalent of {@linkcode hookGuard}, but uses `console.log` for the before and after hook by default.
 *
 * @example
 * ```ts
 * import { logGuard, isNull } from 'type-guard-helpers'
 * const test = {} as string | null;
 * if (logGuard(isNull)(test)) {
 *   test; // null
 * }
 * // hooking to log
 * const hookLog = hookGuard(
 * 		isNull,
 * 		({value, guard}) => console.info(`Calling:`, { guard, value }),
 * 		({result}) => console.info(`Result:`, { result })
 * );
 * ```
