chore: add cache cleaner

[wa0x6e]

🧿 Current issues / What's wrong ?

There is now way to delete all cached contents, in case there was an issue, producing bugged cached contents.

💊 Fixes / Solution

Add a dev script to manually trigger cache clearing. Script only for dev use, and can not be run on prod.

🚧 Changes

• Add script to list the contents of the cache
• Add script to clear the whole cache

🛠️ Tests

To be run only on your locally configured dev storage engine. Do not test with prod settings in your .env or you will wipe the prod cache

Recommend to set your storage engine to file, and add some dummy files to tmp/votes.

• yarn ts-node scripts/list-cache.ts to list the cache contents
• yarn ts-node scripts/clear-cache.ts to clear the cache

Why do we save wrong cached data? This is just for development, in that case, we can easily modify the folder name with VOTE_REPORT_SUBDIR env right?

It’s for rare cases, when the cached data are wrong, like some edge cases we did not foreseen.

Either way, the function to delete files is not wasted, and will be reused in #80

And in cases where cached files contains error, even if we change the cache dir, we still need to clear those files to reduce cost

I feel like it is very easy to delete/rename files on AWS/DO spaces. can merge this but just worried about the unwanted code 🙈
