Recreates the account using BIP-157 approach

DANGER! This method removes all records from the wallet database and creates new ones while the account discovery process.

The Wallet UI should check if the database is empty before calling this method and let the end users to decide whether they want to proceed or not.

This method generates addressBatchSize of addresses, then matches them against the BIP-158 compact filters, and downloads and processes the matched blocks. This method keeps doing the steps until there are WalletConfig.addressGapLimit or more unused addresses in a row. In this case it considers the discovery process completed.

addressBatchSize - the number of addresses we should generate from a keychain to attempt to match in in a rescan WalletConfig.addressGapLimit - the number of addresses required to go without a match before we determine that our wallet is "discovered". For instance, if addressBatchSize=100, and AddressGapLimit=20 we do a rescan and the last address we find containing funds is at index 75, we would not generate more addresses to try and rescan. However if the last index containing funds was 81, we would generate another 100 addresses from the keychain and attempt to rescan those.
