In Memory File System

File System

The filesystem type is a bit specific, as it is a map with key type string and value type *zip.File, I'd like to expand this later, but for now this is all I need.

Manager

File manager is a thin wrapper over aws sdk's s3manager uploader and downloader, meant to be used with mem.File

Mem

mem.File is an in memory file that satisfies the io.WriterAt and io.ReaderAt interfaces. The s3manager uploader and downloader usually read directly from a file pointer and this was created when there is very little disk space to work with (ex: AWS Lambda functions)
