• fix: make Nebula Clang-compatible #160

Description

@veqcc wants to analyze Autoware and Nebula using Clang-tooling, this PR is to make this possible before the (possibly long-winded) merge of develop.

There were two declared, but undefined member functions in the ARS548 HW interfaces that were addressed in

• feat(srr520): initial driver #124

which wouldn't link after compiling with Clang, so I implemented them as printing an error to the console for now (non-breaking change and better than failing silently). @knzo25 please check that this temporary warning is okay.

Fixes #157.
