Price override config and other upgrades

[Tritium-VLK]

1: Abstract manual price override in events where there is no price or there is a pricing error as a config.

Config should be a json file that basically takes address/price. At best it would take address/price/price token, so you could code something in like 1 eth, or 1 bpt, or 1 anything else that does have a price.

Copy the running config into the output directory for each run so that it is clear what configuration each round ran with.

2: Add a flag for pricing problems (fail loud)
Add an additional field to the CSV that has some sort of an error flag where notice to revewers can be dropped. The throw errors like No Price and/or any other isseus that come up direclty into the CSV where they can be seen

3: Calculate based on both the TWAP price and the USD price from fee subgraph data. Add both prices + a delta in the CSV, continue to use TWAP for calculations.

Additional FLAG

Note that if there are no entries or exits yield fees have not been registered. If a pool has not had an entry or exit in more than 7 days, and a flag that says "No join/exit in the last x days"
