Cache corruption with more than 3 KawPow pools

[deh8551]

Describe the bug
When you configure more than 3 KawPow pools, Miningcore, the cache/epochs between the chains seem to become corrupted. Mining core then evicts the cache in favor of the epoch of another chain. Each of the chains then continue trying to use another chain's epoch cache.

I have compiled the latest version, as of 2023-12-30 and am running in docker.

To Reproduce
Steps to reproduce the behavior:
Add 4 or more KawPow chains to config

Here are the entries from the core.log

Not sure if this can be fixed.

Actually, i think the problem is here https://github.com/xiaolin1579/miningcore/blob/48ac4f3a0797de929f4c91732769d6db7fe96015/src/Miningcore/Configuration/ClusterConfigExtensions.cs#L246

All the coins uses the same dictionary key instead of having their own.

I'm working on a fix on my repo, and i think ethash has the same issue.

Yes literally since i posted that reply lol I also already shared the solution with the maintainer of that repo, so he will probably push the fix when he has more free time.

Could you maybe share the solution with me? He hasn't updated in a month
