How to stack this diff:

• Add module ecashaddrjs and util function outputScriptToAddress D13362
• Add util function returnAddressPreview D13363
• Modify parseTx function to iterate over tx inputs and collect slp tokenSend info; new params isTokenSendTx and tokenSendInfo D13364
• Modify parseBlock function to collect tokenIds needed for genesesInfo query D13365
• Add function returnChronikTokenInfoPromise to support Promise.all() calls for token genesisInfo D13366
• Clean up the logic of the try...catch loop in index.js and generateMocks.js so that it is standardized, i.e. you can call the same function on parsedBlock to get parsedBlockWithTokenInfo in both places D13366
• Modify getBlockTgMessage to describe token send txs in telegram msgs D13368

Handle case of message being too long to send (truncate / split into multiple msgs) eliminated in these mocks by linking txid instead of both addresses of token send txs; other outstanding task to handle it in general

• Handle bux token txs that are sent to self, e.g. in block 783465 D13368 ended up having to handle it here to prevent errors in tests
