`decrypt_and_store_transaction` internally serialized transactions, but
the previous commit only added parsing support. Fortunately we already
have the transaction bytes, so to handle this in the short term we can
just pass them through.
Once we have migrated the SDK to latest `zcash/librustzcash` the API
will return to its previous form.
This doesn't affect Sapling note detection (which uses Compact Blocks),
but enables the enhancement logic to decrypt and store the corresponding
transactions for displaying memo fields.
The binary itself was removed in zcash/zcash-android-wallet-sdk#263 but
the `Cargo.toml` was not updated. This didn't affect the SDK itself
because by default it didn't build with the `updater` feature flag.
Move SDK from the root gradle project to its own Gradle module
Move the demo app to be a peer of the SDK
This will simplify integration with CI on Bitrise.
