IByteTransformTransInt64 方法

从缓存中提取long结果，需要指定起始的字节索引，按照字节为单位，一个long占用八个字节
To extract the long result from the cache, you need to specify the starting byte index, in bytes, A long occupies eight bytes

从缓存中提取long数组结果，需要指定起始的字节索引，按照字节为单位，然后指定提取的 long 数组的长度，如果传入 10 ，则表示提取 10 个连续的 long 数据，该数据共占用 80 字节。
To extract the long array result from the cache, you need to specify the starting byte index, in bytes, and then specify the length of the long array to be extracted. If 10 is passed in, it means to extract 10 consecutive long data. Occupies 80 bytes.

从缓存中提取long二维数组结果，需要指定起始的字节索引，按照字节为单位，然后指定提取的 long 数组的行和列的长度，按照 long 为单位的个数。
To extract the result of a long two-dimensional array from the cache, you need to specify the starting byte index, in bytes, and then specify the length of the rows and columns of the extracted long array, in long as the number of units.
