Initial migration to typescript (#845)

This migrates some utilities classes from javascript to typescript.
Nothing special about the migration, mainly added types and made sure
the code adheres to the strict mode.

I have picked some small files so git doesn't think they are the same
since they are "very different".
I hope that in later PRs, when migrating lager files this won't be an
issues.
