Local player should be able to see when users are spectating them (and how many)

[peppy]

and potentially list the users somewhere, similar to stable.

Discussed in https://github.com/ppy/osu/discussions/21929

^{Originally posted by poettig December 29, 2022} In Stable, it is shown in the upper left corner who is currently spectating you. In Lazer, this is missing (or I am overlooking something).

Is this on purpose or just "not implemented yet"? If the former, what is the reasoning?

IMO this would be a good "default on, but can be disabled in options" feature.
