Replace lru_cache with cache

[dekkers]

Changes

We don't use the LRU functionality of lru_cache so we can change it to the functools.cache

QA notes

Only the cache function is changed in bytes and bits, so a simple check that the basic KAT functionality of boefjes/normalizers and bits still work should be enough.

Nice one. I've confirmed that there are no other references to lru_cache

Checklist for QA:

• I have checked out this branch, and successfully ran a fresh make reset.
• I confirmed that there are no unintended functional regressions in this branch:
  • I have managed to pass the onboarding flow
  • Objects and Findings are created properly
  • Tasks are created and completed properly
• I confirmed that the PR's advertised feature or hotfix works as intended.
• I checked the logs for errors and/or warnings and made issues where necessary

What works:

Seems to work as expected. Onboarding works, enabled extra boefjes which also run. Normalizers run and parse data. The normalizer links work on the Tasks list.

What doesn't work:

n/a
