Fee Collector: Historical per pool summary

[Xeonus]

To further enrich the protocol fees page, we shall create a summaries file similar to this one: https://github.com/BalancerMaxis/protocol_fee_allocator/blob/main/fee_allocator/summaries/recon.json

Ideally a json with following information:

1. poolId
2. gaugeId
3. arrays of fees earned, and fees distributed per epoch

In that manner we can plot / visualize per pool / gauge stats that give us insight for historical performance and make it easier for us to put the active fee run into context.

Directly doing API calls / calling the raw run files is inefficient. A summary json file that is created in a similar fashion like the recon.json would be ideal.

@Xeonus can you maybe provide an example output? Or do we not need this anymore (can you close it if so)

If we are still interested in per pool performance stats / overall stats over time, I think this is valuable. We could simplify the logic and build automation based off the csvs to create a combined json file? An entry could look something like this:

{
  "combined_pool_data": [
  {
    "poolId": "0x...",
    "chain": "mainnet",
    "symbol": "rETH-STABLE",
    "starting_epoch_timestamp": 169xxxx,
    "earned_fees": [123, 123, 123,123],
    "fees_to_vebal": [123, 123, 123,123],
    "fees_to_dao": [123, 123, 123,123],
    "total_incentives": [123, 123, 123,123],
    "aura_incentives": [123, 123, 123,123],
    "bal_incentives": [123, 123, 123,123],
    "redirected_incentives": [123, 123, 123,123],
    "reroute_incentives": [123, 123, 123,123],
  },
  {
   ...
  },
 ]
}

After speaking to @Xeonus and better understanding requirements we agreed to the following.

1: Change the code such that report csvs include the round end date on each line
2: Backfill all historical csvs to have the end date included
3: Create a new github action to concationate all the CSVs together (making sure there is no duplication of pool/chain/end_date)

Solved by #159. Awaiting review.
