Serialize an object with information about file
to TDLib and Bot API compatible Unique File ID
Unique File IDs can't be used to download or reuse files,
but they are globally unique, meaning that the same file will
have the same unique ID regardless of the user who created
this ID (unlike normal File IDs, that also contain user-bound
file access hash)
