两个Enum，一个26个元素，一个130个元素。
分别循环1000000, 10000000, 80000000进行contains(),add(),remove()操作。
对比EnumSet和传统的Set数据结构的性能：

由于基于Mac个人机进行测试，存在一定的误差，基于80000000的Loop可以看到：
RegularEnumSet
- contains: 2.5%
- add: 14.3%
- remove: 4.3%
JumboEnumSet
- contains: 15.6%
- add: 10.1%
- remove: 7.8%
Random存在耗时，会导致性能更接近，因此，该提升数据存在一定的不精确性，但是可以明显的看到。无论是RegularEnumSet还是Jumbo，均存在明显的性能提升。
