Create a Desktop Tool helper class in @kiva/ssirius-react

[natesulat]

I'd like to make a helper class that makes it easy to get data from https://github.com/kiva/protocol-desktop-tool. It will probably be an implementation of some FPScanner interface that we use to standardize the capabilities of fingerprint scanning utilities, but given that fingerprint scanning relies on specific pieces of hardware, I think it makes sense to have specific implementations on a per-scanner/tool basis.
