Problem description

The logger applies text styling that only work in the terminal, if we use the log file env var or redirect stdout to a file then we end up with

^[[38;2;000;128;000m                  Metal^[[0m | ^[[1m^[[38;2;100;149;237mINFO    ^[[0m | Initializing device 0. Program cache is NOT enabled
^[[38;2;000;128;000m                  Metal^[[0m | ^[[1m^[[38;2;100;149;237mINFO    ^[[0m | AI CLK for device 0 is:   1000 MHz
^[[38;2;000;128;000m                  Metal^[[0m | ^[[1m^[[38;2;100;149;237mINFO    ^[[0m | Enabling program cache on device 0

What's changed

Modify the logger to disable all fmt styling if the output isn't a tty.
