spellcheck: add a spellcheck script + apply spelling fixes (#58)

Summary:
This adds a `script/spellcheck.sh` which runs through all the files and validates that there are no spelling mistakes. The wordlist is rather specific so not setting up any CI for this since it's a pretty high burden per commit to keep the wordlist up to date.

Pull Request resolved: #58

Test Plan:
```
scripts/spellcheck.sh
scripts/lint.sh
pyre
pytest
```
