Use logger directly

[inancgumus]

This issue is a continuation of the previous Proper Logger issue of grafana/xk6-browser#54.

Previously we added several log calls in this PR of grafana/xk6-browser#131.

Next todo:

• Remove the custom logger
• Report caller by default
• Strip the module info from the reporter caller
• Provide the function name in the caller
• Colorize logs

Feel free to add more to this list. I worked on some WIP commits to roughly solves some of them, see: x, y.

Trivia:

Morty Smith C-137 in reference to the designation given to his grandfather by the Trans-Dimensional Council of Ricks, in reference to his original universe, "C-137", whether this is his actual universe designation is unknown.
