This module provides a lightweight implementation for printing to the console
and updating previously-printed console lines. It used by [[fpm_backend_output]]
for pretty-printing build status and progress.
@note Note
The implementation for updating previous lines relies on no other output
going to stdout/stderr except through the console_t object provided.
@note Note
All write statements to stdout are enclosed within OpenMP critical regions
