ibc-proto-rs v0.32.1
*July 31st, 2023*

This release includes default `serde` value for token transfer memos and fixes
the issue with deserialization of `MsgTransfer` and `FungibleTokenPacketData`
types when no memo is present.

- Fix token transfer deserialization for cases with no memo by deriving
  `Default` serde for the memo field in `MsgTransfer` and
  `FungibleTokenPacketData` types.
  ([#119](#119))
