feat: enable IBC withdrawals for all tokens

[emccorson]

This PR allows IBC withdrawals for all assets, instead of just NAM.

There is still zero indication to the user about whether the transaction failed or succeeded, but for testing this information should be displayed in the console.

---

Changed

• Use base denom amounts when building IBC transfers with JS SDK
• Use unknown gas limit value for txs without an indexer type

Added

• Enable IBC withdrawals for all tokens. Closes Namadillo: IBC -> Display all available tokens for withdraw and remove prototype code #1242

Fixed

• Use same gas limit and price for IBC withdrawal as rest of Namadillo
• Reveal public key if needed for IBC withdrawal. Fixes Namadillo: IBC -> IBC withdraw should reveal public key if needed #1222

LGTM!

I think we need to discuss how we're going to organize the types in the codebase. One advantage of having them in a root folder is that is easy to find, import, and maintain. Do you think we should break the types in different files?

I actually did this just because I needed a const and I couldn't do that in types.d.ts. Now that your PR changes it to types.ts, we could still use that but I'll leave that until we discuss how to handle it.
