...instead of monkey patching the console log objects. We use a logging
framework everywhere now (this fixes the times when we didn't...)
so there's not really a reason to do this the hacky way anymore.
This means that log lines now appear to come from whatever else is
intercepting the logger (eg. sentry) rather than rageshake.ts.
Opinions on this welcome on whether it's better or not.
This upgrade came with a number of new lints that needed to be fixed across the code base. Primarily: explicit return types on functions, and explicit visibility modifiers on class members.
by fixing the cause rather than the symptom: this upgrades the code to use the new, recommended JSX transform mode of React 17+, which no longer requires you to import React manually just to write JSX.
