neofs-cli object get doesn't write header to file

[vkarak1]

I expected to see two new files when running neofs-cli object get with --header and --file flags, but I see only one file with object payload.

Steps to Reproduce (for bugs)

root@az:/home/service# neofs-cli object put   -g  -r node1:8080  --cid 9RP8Wtjpe2sj4KAvmUBrbjE1xU1NwFDZJiiwQ11Vkk4Z --file /etc/neofs/storage/tatlin-object-sber-tfstate/vkarakozov/object1 -t 100m

@vkarak1 to print header in file we need to marshal it in json or proto. But there are no flags --proto\--json in object get command.
Looks like we need to add these flags.
@fyrchik, should we choose some format by default or we need to reject writing?

[acid-ant]

Also we already have flag --binary which is similar to proto.

[carpawell]

IMO there is no use-case for dumping the header only in proto format.

[acid-ant]

Flag --proto we are using in commands get/head, --binary in delete/get/put.
How about to use --binary instead of --proto and in get write header in file in binary format if flag --header provided?
And do the same in command head if flag --file provided.

[fyrchik]

I vote for removing --header, it seems too complex and you can always use object head if needed.
