Subv 5165b63512 Services/AM: Support using FS subfiles with the CIA-related service functions. 
FS subfiles are created with File::OpenSubFile, they have a start offset that must be added to all read/write operations.

The implementation in this commit is done using a new FileBackend that wraps the FS::File along with the start offset.
