Obviously not a critical-path priority piece of work, but I think it is really nice (striking, unique, dare I say fun), when terminal programs have a logo/banner which displays the library name at the start of the terminal output, e.g. as for or . I think we should add one for CATS, but this may be a controversial opinion, so let's treat this as a suggestion for now! (Though if there is agreement to go ahead, I can easily set this up.)

The exact ASCII art text can be chosen at a later stage, with ASCII generator sites like this one creating the art for one to choose from, but the idea is something like this which will be seen when someone runs cats (though perhaps we can enable it to now be shown if someone specifies via come CLI or config file option):

$ cats -d 90 --loc RG2                                                                      ─╯
 __     __   _____  __  
/ /`   / /\   | |  ( (` 
\_\_, /_/--\  |_|  _)_)

or some other stylistic text choice e.g:

 / _| / \|_ _/ _|
( (_ | o || |\_ \
 \__||_n_||_||__/

             __         
.----.---.-.|  |_.-----.
|  __|  _  ||   _|__ --|
|____|___._||____|_____|

etc. (showing examples on the smaller side since we don't want anything to overhwhelm/dominate the output).

Colours can also be set for standard-supported terminal colours, but we don't have to go crazy with it (not that I would mind adding a little colour, as long as it doesn't in any significant way ramp up the carbon required to run, of course). 😄
