Add Stacks (STX) Support

As the title says.

I know there is a coin with the same symbol already supported on Trust called Stox, but Stacks is the 75th largest coin by market cap compared to Stox miniscule $1 million market cap. I don’t really understand why the top 100 coins aren’t already all supported by Trust (HBAR is another weird example). It’s a project with huge potential given how it enables BTC to be used with smart contracts and other DeFi tools. Its also being fully regulated by the SEC since the project is being developed fully in the US.
