Update 'set-permission EditSequence' command

[bookdude13]

Current: ./proton_cli set-permission <admin-key> (add | remove) <uid> EditSequence <target-sequence>
Desired: ./proton_cli set-permission <admin-key> (add | remove) <user-name> EditSequence <seq-name>
Reason: Changing variable names to be clearer. Also using user name, not id, to be easier for user
