Namada 0.25.0

This release includes only the new genesis flow.

FEATURES

• Added bech32m string encoding for common::PublicKey and DkgPublicKey.
  (#2088)
• Added --pre-genesis argument to the wallet commands to allow to generate
  keys, implicit addresses and shielded keys without having a chain setup. If
  no chain is setup yet (i.e. there's no base-dir or it's empty), the wallet
  defaults to use the pre-genesis wallet even without the --pre-genesis
  flag. The pre-genesis wallet is located inside base-dir in
  pre-genesis/wallet.toml.
  (#2088)
• Reworked the genesis templates, setup and related utils commands.
