Implement MS-CFB container for full password protection

[nkryuchkov]

Description

Right now the password protection is implemented according to the ooxml specification. It works correctly but it is not intended to prevent the file from being opened without the password prompt. Password protected files should not be saved as zip containers, instead they should be saved as MS-CFB containers according to the following specification: https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-cfb/53989ce4-7b05-4f8d-829b-d08d6148375b . MS-CFB should be implemented to allow full password protection
