The Migration Facet contains functions related to Silo V3. Farmers are required to migrate to the new accounting system created by the Silo V3 upgrade.
Migrates a Farmer's Deposits from the old (Seasons based) to the new Silo (Stems based) accounting system.
When migrating an account, a user must submit all of the account's Deposits or the migration will not pass because the Seed check will fail. The Seed check adds up the BDV of all submitted Deposits, multiplies by the corresponding Seed amount for each token type, then compares that to the total Seeds stored for that user. If everything matches, the migration is valid.

Gets balance of Seeds for a Farmer that hasn't migrated.
