class SwiftPackReader(object):

A SwiftPackReader that mimic read and sync method

The reader allows to read a specified amount of bytes from a given offset of a Swift object. A read offset is kept internally. The reader will read from Swift a specified amount of data to complete its internal buffer. chunk_length specify the amount of data to read from Swift.

Method	`__init__`	Initialize a SwiftPackReader
Method	`read`	Read a specified amount of Bytes form the pack object
Method	`read_checksum`	Read the checksum from the pack
Method	`seek`	Seek to a specified offset
