[Tooling] update pyspelling in SDK to support camel-case

Reproduction steps / Feature

newer versions fixed the camel-case option to aspell. The spec repo uses this version. We should update the SDK to do the same. Then we can remove some of the excluded files from the spell checker.

It's also unclear why we have two spell checkers running - it's probably worthwhile to consolidate these.

After updating, we should also prune the wordlist to exclude the things that were added to work around not having camel case. When we did this in the spec, we found lots of spelling errors.
