Describe the contribution

• Fixes Syslog writes during initialization could be converted to events #215
  • Error/failures paths during initialization (after EVS registration) have been converted to generate events instead of syslog writes.
  • These are standard 'set-up' calls and will likely remain in adaptations of the sample app. Also, this is the standard pattern in the rest of cFS.

Testing performed
GitHub CI actions all passing successfully and tested locally with cFS suite to confirm events text formatted correctly etc.

Expected behavior changes
Errors during initialization (after EVS registration) will generate events now, rather than syslog writes.

System(s) tested on
Debian GNU/Linux 11 (bullseye)
Current main branch of cFS bundle.

The error paths in ProcessCmd and GetCrc should probably also be converted to events - happy to add those in to this PR before this is merged - just let me know.
