transferit-py: reconstructing transfer.it upload and download exchanges

transferit-py reconstructs transfer.it file-transfer exchanges from its public web client and implements Python library and CLI clients. Its research maps MEGA-backed API commands, ephemeral sessions, AES-128-CTR encryption with CBC-MAC and WebSocket upload framing. The client uploads folders and streams decrypted downloads.
