Implement FileIndex

[devillove084]

• Implement basic IO Module
• Implement a FunctionVistor(may be a simple one for poc) and FieldRef for FileIndexReader
• Implement FileIndexFormat and FileIndexWriter/Reader and other interface
• Implement BitmapFileIndex
• Implement BloomfilterFileIndex

Regarding the work of implementing FileIndex, I will split it into multiple PRs to facilitate review and comment, so that there will be no problems in the implementation due to deviations in my personal understanding.

I've made some effort to separate the following implementation. If you have any suggestions for further improvement, please let me know. cc @Xuanwo
