rpc methods don't work anymore

[magmel48]

have the following code:

const client = new rpc(node, 'mainnet');
console.log(await client.getBalances('bnb14spch0j94ya2w3fe49uf3lw9ee7vfwp8q5jups'));

error thrown:

Error: field type is not expected
    at /Users/xxx/yyy/core/node_modules/@binance-chain/javascript-sdk/lib/amino/decoder/index.js:164:15
    at Array.forEach (<anonymous>)
    at decodeObjectBinary (/Users/xxx/yyy/core/node_modules/@binance-chain/javascript-sdk/lib/amino/decoder/index.js:131:8)
...

I suppose all amino decoder is broken, maybe some new rules were not applied. The library is useless for using RPC except "raw" methods like abciQuery, etc.
