Fixed unblinded output formatting.

[Randy808]

To run locally, npm install and use the following snippets:

# Liquid
export API_URL=https://blockstream.info/liquid/api
export PORT=5000
source flavors/blockstream/config.env
source flavors/liquid-mainnet/config.env
npm run dev-server

---

To test:

• Download wallycore.js and wallycore.wasm located at https://blockstream.info/liquid/libwally/wallycore.js and https://blockstream.info/liquid/libwally/wallycore.wasm respectively
• Make a folder called libwally in client/src/lib/ and place the 2 downloaded files in there
• Add the following lines to dev-server.js after the line router.get('/app.js', browserify(rpath('client/src/run-browser.js'))):

router.get('/libwally/wallycore.js', (req, res) => res.sendFile(rpath('client/src/lib/libwally/wallycore.js')))
router.get('/libwally/wallycore.wasm', (req, res) => res.sendFile(rpath('client/src/lib/libwally/wallycore.wasm')))

• Now download assets.minimal.json from https://blockstream.info/liquid/_data/assets.minimal.json and put it in www/_data (making the directory if it's not there)
• Visit http://localhost:5000/liquid/tx/e6d8feb9a539628fe9386570fc6c546315a1ce37d64ce104fc742545c45102ea#blinded=100,f266a3f15e78b71481adfedff9aefe47c69501a181ffc68527bb5fb26da6a4b2,3d48822703130651d51583438f5d4692b337b9483a1b4d81d158672a4f288838,7dadf08a4b5750f4795a48f7ede24732ea6efca3dc46c51806d332fdd6464cc3 and verify the output is unblinded with the formatting presented in the screenshot below
