Improvements and ToDo List

[eabase]

Here's the in-code ToDo list.

• Move this list into repo issue or README file. (And remove from script code.)
• Add a "max" line to the VRAM precentage bar. Also add a reset key (trap), while running.
• Remove all shellcheck statements, as it is not useful/compatible with this script.
• Separate out BAR_COLOR and use only one percentBar() line in print_vram_bar()
• [1][cancelled] Add automatic detection of GPU Max power level in get_card_powers() - Already obtained in poll()!
• Add automatic detection of GPU Max clock rate in get_card_powers()
• Add column for current SM clock rate.
• [cancelled] Fix colors of data line for newly added (pstate) column items
• Move VRAM "progress" bar into VRAM cell (need 2 lines) using a "thin line" UTF-8 character (\U258?)
  (We could also use the bottom border itself as the colored bar!)
• Automate the Legend %-values, by using graphics card own settings. See [1]. This would reduce the card customization tuning by 2 items. [Max power, Max Temperatures]
