text: Title: [BUG] Error for pandas memoization is confusion
  Body: **Describe the bug**
  
  A user asked questions about the following error:
  
  ```
  Failed memoization speedup attempt due to Pandas internal hash function failing. Continuing without memoization speedups
  ```
  
  We can give a more constructive response like `... This is fine, but for speedups around skipping re-uploads of previously seen tables, try identifying which columns have types that Pandas cannot hash, and convert them to hashable types like strings.`
