Passing configuration via tsconfig instead of tsc-strict parameters

Hi,

thx for this extension. I checked this plugin out a couple of months ago, and I am sure that I am not crazy and remember that it was possible to pass the configuration for `strictNullChecks` via `tsconfig` instead of passing it as an argument `--strictNullChecks`.

Nevertheless I do not remember, where I read that.

Is it possible to set the strict-config via `tsconfig.json` instead of passing each of them as a parameter to `tsc-strict`? Or am I crazy?
