feat: add remove cache method

[kavience]

what ?

for solve issue https://github.com/StructureBuilder/react-keep-alive/issues/82, I add remove method.

为了解决 issue https://github.com/StructureBuilder/react-keep-alive/issues/82, 我添加了一个删除缓存的方法。

How to use ？

<KeepAliveProvider
    ref={(ref) => {
    this.keepAliveProviderRef = ref;
    }}
    max={30}
>

</KeepAliveProvider>

First you need get keepAliveProviderRef, and in correct time call it's method named removeCache like this:

首先，需要获取 keepAliveProviderRef ，并在合适的时间调用名为 removeCache 的方法，如下所示：

keepAliveProviderRef.removeCache('KeepAlive');
// or
keepAliveProviderRef.removeCache(['KeepAlive']);

removeCache receive string or string array as params which is name of KeepAlive.

removeCache 接收字符串或者是字符串数组作为参数，参数来源于 KeepAlive 的属性 name。

<KeepAlive name="KeepAlive">test<KeepAlive>

Note

If you use react-router, and need use history.push when removeCache, you must use history.push first and then use removeCache.

如果你使用 react-router, 你必须在使用 removeCache 之前调用 history.push

临时使用方法：

修改 react-keep-alive 版本为我的地址库

    ......
    "react-keep-alive-pro": "^2.5.5",
    ......

其它功能使用方法不变，仅添加一个 removeCache 方法。
