Can't parse a tx (Any). Get a signature error

[andynog]

Upgrade to cosmos v0.3, and now when trying to parse a tx I'm getting a signature error

This line is where the error is thrown https://github.com/andynog/cosmrs-tx-example/blob/0f25f3e00cfbff3367e451098809d9739d3c77ca/src/main.rs#L52

When running I get:

Getting messages for transactions in height 5258498
Error converting tx: Block 5258498 - Height "E4AD2D2B27CB57AA2B273F4E872B3BC83D9E189B670AAEFDB50A790974D18FE1" - Error: signature error

Location:
    /rustc/09c42c45858d5f3aedfa670698275303a3d19afa/library/core/src/result.rs:1915:27

the TxResponse has a tx property that is an Option<Any>, so I try to get the value as bytes

let tx_result = Tx::from_bytes(tx.value.as_slice());

So it is most likely failing to decode the bytes into the Tx proto in the code below ?

impl TryFrom<&[u8]> for Tx {
    type Error = ErrorReport;

    fn try_from(bytes: &[u8]) -> Result<Tx> {
        proto::cosmos::tx::v1beta1::Tx::decode(bytes)?.try_into()
    }
}

Here's the transactions details (with bytes at the end):

[tony-iqlusion]

Right now it's using Vec<secp256k1::Signature> to model the signatures, which doesn't work with these Amino multisignatures.

I'd suggest changing that to be Vec<Vec<u8>> in the next breaking release, to support any signature type.
