Stride MsgLiquidStake and MsgRedeemStake

[emidev98]

Basic Stride functionality to create an LSD from a native coin and redeem the native coin from the LSD. Code Example:

import { MsgLiquidStake, LCDClient, MnemonicKey, Wallet, isTxError } from "@terra-money/feather.js";

const lcd = new LCDClient({
    "stride-testnet-1": {
        "lcd": "https://stride.testnet-1.stridenet.co/api",
        "chainID": "stride-testnet-1",
        "gasAdjustment": 2,
        "gasPrices": {
            "ustrd": 0
        },
        "prefix": "stride",
    },
});
const acc = new MnemonicKey({
    mnemonic: "...",
    coinType: 118
});
const wallet = new Wallet(lcd, acc);

(async () => {
    const liquidStakeMsg = new MsgLiquidStake(
        "...",
        "100000",
        "uluna"
    );

    try {
        const lsdMsgTx = await wallet.createAndSignTx({
            msgs: [liquidStakeMsg],
            chainID: "stride-testnet-1",
        });
        const sendTxResult = await lcd.tx.broadcastAsync(lsdMsgTx, "stride-testnet-1");
        console.log(sendTxResult);
    } catch (e) {
        console.log(e);
    }
})();
