syncing nearby robots without hard-coding

[IsmailMohid]

should be able to have an option on the controller to broadcast out a message to nearby robots requesting their mac address. if successful, add mac address and name of robot/team to a vector stored in EEPROM (although esps don't have eeprom i think so its just in a section of flash) so don't have to sync every time.

potential issues:

• eeprom is only 512 bytes, so if we're storing team names space can run out really fast
  • could have character limit for team name? maybe limit to just a 4 letter acronym like advanced projects?
    - would also let us standardize the block size of a team's info and not have to use null-terminators
  • can structure as a circular queue where least recently added macs are popped out to RAM so they stay in memory at least until controller is turned off,
    - if so, could add a power button to controller so that we can only update data on start and end pointers when controller is turned off
    - would be nice for wear-leveling
    - add a dirty bit maybe to track if a write is necessary for those pointers
• with 512 bytes and 10 byte blocks can have 50 teams stored and start and end pointers

also necessitates that we can manually delete addresses in debug menu.
