transfer_token.go outdated, needs update, example provided

Current transfer_token.go is outdated. Unsure of when this happened but the current method of transacting ERC-20 tokens looks something like this:

Note: This is done from my own research, this may not be best practice but it has worked as a PoC. It may also be worth mentioning I created the token mentioned in the comments using https://vittominacori.github.io/erc20-generator/ & transferred to MetaMask first. Then sent the tokens to my local geth account running on a light node. Hopefully this helps someone.
