Launchpad. Two new classes are provided: `LedgerSigner` (for most use cases)
and `LaunchpadLedger` for more fine-grained access.
- @cosmjs/math: Add `.multiply` method to `Decimal` class.
- @cosmjs/math: Deprecate `Uint32.fromBigEndianBytes` in favour of
`Uint32.fromBytes`, which supports both big and little endian.
- @cosmjs/math: Deprecate `Uint64.fromBytesBigEndian` in favour of
`Uint64.fromBytes`, which supports both big and little endian.
- @cosmjs/math: Add `Uint32.fromString`.
- @cosmjs/tendermint-rpc: Make `BroadcastTxCommitResponse.height` non-optional.
- @cosmjs/tendermint-rpc: Make `TxProof.proof.leafHash` non-optional because it
is always set.
