st_record.py: Better TUI display, exit on failing rich import

Browse Source 
In TUI mode, bar displays are now hidden by default until its
diagnostic metric was received to declutter the UI.
This means that for instance the compression metrics are hidden
when this feature is not utilized in the traced program,
or all metrics are hidden if it does not call `st_diagtrace`.

The bars are now styled to not give an impression of being
a progress bar. The completed portion is colored gold while
a completed bar is indicated by red, as this usually
indicates a new maximum value.

A failing rich import in TUI mode now exits after
its error message.
