@hinto-janai this is ready, it's not extremely high priority, I have stuff I can work on that does not depend on this. I may have rushed some docs as this took way longer than expected, so I might need to expand some sections. |

What
Adds alt-chain handling to our consensus code.
part of: #194
How
Handling of alt blocks/chains is delicate balance, we need to check alt block weight however the amount of data needed to check block weight is too much to do for any alt block.
So handling of alt blocks is done in steps.
Going roughly, first we build the difficulty cache and check the blocks PoW. Then if that is valid we build the weight cache and check block weight. This means we need to add multiple new request to the context cache.
Also to prevent needing to build the caches multiple times we keep the alt caches cached in the context cache.
Some changes had to be made to the database requests/response types.
