Description

gsl-lite recommends that libraries use it through the ::gsl_lite namespace, possibly by a namespace alias in their own namespace. source and rationale: https://github.com/gsl-lite/gsl-lite#using-gsl-lite-in-libraries
For this reason, I created "utils/gsl.h" with the intention of it being the common entry point from minifi to gsl, including a namespace alias of ::org::apache::nifi::minifi::gsl to ::gsl_lite. Please use the "utils/gsl.h" header and the gsl namespace alias instead of directly including "gsl/gsl-lite.hpp" and referring to ::gsl.

This issue is for submitting a PR that fixes the one occurrence where this is not followed.
