Add Filter Immortalized Crew in Retrieval Menu

Travis S McClain

Just what the discussion title says. Make the filter optional, since there are players who want duplicates of specific crew, but make it an option. Yes, I know they can be sorted by fuse level which groups immortals at the top. It's still obnoxious to have to scroll through them. For instance, I was checking to see how useful the Explorer polestar would be for me and whether I wanted to sell it. I have 50/88 in that pool immortalized. It would be considerably more convenient to only look at the 33 I either haven't finished fusing or don't yet have.
