Terra: add autogenerated assetlist and images

[zhongfu]

Changes:

• Existing (native) assets should be largely unchanged (except for updated images and the addition of denom aliases)
• Indentation was changed to 2 spaces per level
• White Whale address updated with mainnet address (instead of testnet address), and name changed to match Terra CW20 token list

Other things to note:

• Display names are all set to lower(symbol)
• CW20 tokens were largely imported as-is from the Terra CW20 token list, so some tokens have weird symbols, e.g. "mIAU (Delisted)"
• None of the new tokens have CoinGecko IDs or descriptions
• There's one duplicate symbol for "ChainLink Token" and "Chainlink (Portal)"

I don't think we should be changing symbols of tokens, which makes me think we shouldn't have (delisted) as part of the symbol, image name, or denom, but that it'd be appropriate fine for the 'Name' field.

I've got some ideas:

• strip "(Delisted)" out of symbol (and display), and add it to the name, if it isn't already in there
• replace the info in the terra cw20 list with onchain info, where available
• send a PR to remove the "(Delisted)" bits from the terra cw20 list

Will you be doing that first idea (moving the 'delisted' over to the Name field) in this PR? or you prefer I do that manually after?

alright, i've gone ahead and done that (+ fixed the PAXG image, and verified that all of the images are actually images)
