1.2.1

[Scitz0]

Description

Various patches for 1.2.0

• Fix for when both key and script was registered with same hash
• Fix for drep_script format according to CIP-105, implementation was in conflict with pre-defined roles
• Pool stat fix, rollback to previous code until DBSync gets a fix
• Replace usage of view column with own bech32 utility functions
  • Utility function for stake_address encoding/decoding
  • stake_address.view references
  • Cache data that rely on bech32 format for stake account
  • Any cache references that rely on stake account in bech32 format
  • pool_hash.view references
  • Cache data including bech32 format for pool IDs
  • Any cache references that rely on pool ID in bech32 format

Cancelled:

• DRep view references - cancelled due to presence of pre-created roles in dbsync
• multi_asset > fingerprint references - requires addition of blake2b extension, TBC - if/when dbsync retires bech32
• Truncate (delete from) multi_asset.fingerprint, stake_address.view column and corresponding indexes to save on disk space and background maintenance on Postgres DB => In absence of tx_out.address, the primary benefactor of this would be multi_asset.fingerprint, but that's currently not being handled in this release - Hence, skipped this item accordingly
