Devs SBAT to resolve the multipliers that are required for the GCSO

[diminator]

The multipliers are hosted on a public spreadsheet and need to be made available to the leaderboard app. Potentially crawled and indexed by blockscout

• We will need to extract from the spreadsheet a list of tuples of (address, multiplier) .
• the sheet will calculate multiplier by summing up a bunch of other data -- that could be in columns, or it could be a separate table that logs "Address" "Multiplier Reward" and we add them up with a SUMIF.
• The sheet should be world-readable and only writeable by Claire and Marek.
