1900 年至 2100 年公历、农历互转

* Solar : 公历 阳历
* Lunar : 农历 阴历

支持年份：`1900-2100`

## 用法：

```js
import solarLunar from 'solarLunar';

const solar2lunarData = solarLunar.solar2lunar(2015, 10, 8); // 输入的日子为公历
const lunar2solarData = solarLunar.lunar2solar(2015, 8, 26); // 输入的日子为农历
```

output:

```js
{
    lYear: 2015,
    lMonth: 8,
    lDay: 26,
    animal: '羊',
    monthCn: '八月',
    dayCn: '廿六',
    cYear: 2015,
    cMonth: 10,
    cDay: 8,
    gzYear: '乙未',
    gzMonth: '丙戌',
    gzDay: '丁巳',
    isToday: false,
    isLeap: false,
    nWeek: 4,
    ncWeek: '星期四',
    isTerm: true,
    term: '寒露'
}
```

## API

* (Object)`solarLunar.solar2lunar` : 输入的日子为公历年月日

  * 参数 : (Number)年,(Number)月,(Number)日


```js
solarLunar.solar2lunar(2015, 10, 8);
solarLunar.solar2lunar(2015, 10, 08); // 等价于上者
```

* (Object)`solarLunar.lunar2solar` : 输入的日子为农历年月日

  * 参数 : (Number)年,(Number)月,(Number)日


```js
solarLunar.lunar2solar(2015, 8, 26);
solarLunar.lunar2solar(2015, 08, 26); // 等价于上者
```

* (Number)`lYearDays` : 返回农历 y 年一整年的总天数

  ```js
  const count = solarLunar.lYearDays(1987); //count=387
  ```

* (Number(0-12))`leapMonth` : 返回农历 y 年闰月是哪个月；若 y 年没有闰月 则返回 0

  ```js

  ```

* (Number(0|29|30))`leapDays` : 返回农历 y 年闰月的天数 若该年没有闰月则返回 0

  ```js
  const leapMonthDay = solarLunar.leapDays(1987); //leapMonthDay=29
