Can't create flag in room with no creeps in it.

[Mirroar]

Trying to create a flag using RoomPosition.createFlag in a room with no creeps in it fails.

let destinationPos = new RoomPosition(25, 25, roomName);
destinationPos.createFlag(flagName);

Game console output:

Error: Could not access room W3N7
    at . ([...]\steamapps\common\Screeps\server\node_modules\@screeps\engine\dist\game\rooms.js:1444:19)
    at .createFlag (evalmachine.:1:72)

Private server version is 2.3.0

You cannot perform any operations on a room in which you have no visibility (creeps or structures).

You can create flags in rooms without vision through the GUI, thus the reasoning why the code should perhaps be able to as well.
Currently your code has to create the flag in a room with vision and then move it to the room that has no vision on the next tick.

The intents allow for creating flags without vision, however, we can not due to createFlag() only existing on the Room objects.(RoomPosition.createFlag() would be an amazing fix for that)

@TheRealMaxion I did not know about that trick. Thanks!

@ags131 RoomPosition.createFlag() sounds like a good idea. Any idea why it doesn't already exist?

[TheRealMaxion]

@sparr it exists but it uses the room object internally

[sparr]

Proposal: move most of the relevant code to RoomPosition.createFlag() and have Room.createFlag() call that, instead of vice versa?

Any update? The inability to create flags in remote rooms is very annoying.

@Strikeeaglechase Contribution to my PR may help move this along. I wasn't able to get it working before I stopped playing, but it was really close.
