[Feature] Make high scores more personal

[RoddieKieley]

Is your feature request related to a problem? Please describe.
At the moment the high score entries look like

• generated-podname score
  e.g.
• qpid-5-a8y42 32767

where the podnames generated are similar to what real pod names would be if they were not a part of a statefulset

Describe the solution you'd like
It has been discussed that a desire exists to move to a model where we have

• 3LTR PODNAME SCORE
  e.g.
• RNK proton-6-b9z53 65535

so that players could input their three letter initials to go along with the existing mechanism.

Describe alternatives you've considered
If this was a part of a specific authenticated installation deriving identity from there might make sense but is likely overkill in this case.

Additional context
As Pod Escape is a somewhat arcadey experience the three letter, for three player initials, likely makes sense for the moment.
