Add in spell checking

[William-McGonagle]

The spell-checking should use the built-in dictionary stored on Unix/Linux machines. We don't need to depend on any more NPM packages, especially if those packages store an entire dictionary along with them. This spell-checking should occur during the build process, and cause the project to crash if it fails (making it so that we can't launch misspelled standards).

I know the crashing seems like it will be annoying in the future, but it will ensure that we don't have any badly-done standards representing the FPA Vault.

If you want to claim this issue, let me know!

Cheers,
Will
