Supports ignorePaths option

[alexdeia]

A little PR to improve the configuration.

Before these changes, I did something like this

    this.use(async (ctx, next) => {
      if (ctx.url === '/api') {
        await next();
      } else {
        await logging({
          logger,
          overrideSerializers: false
        })(ctx, next);
      }
    });

After I can use this

    this.use(logging({
      logger,
      ignorePaths: ['/api'],
      overrideSerializers: false
    }));
