The only thing I'm unsure about is the stabilizer calculation. Right now, I'm just using the DOLA supply in DAI.

I also need us to confirm what is the start time we should use, for now I just picked the first anchor tx.

Attached is a zip of various reports. The CSV generation doesn't work. tvl.zip

Updated the stabilizer TVL calculation to use Stabilizer.supply() and changed category to assets

New TVL files are attached. tvl.zip

Set start to vaults launch. Added logic to only include anchor TVL after anchor launch block #.
