Add support for redcatOS

[RedPCat]

Hi, I'd want support for my OS, redcatOS. I am currently working on it and want neofetch support as the logo currently is tux.

Description

Adds a new logo for neofetch on redcatOS Systems.

Features

New Logo

If redcatOS is based on Linux, it shouldn't be placed in the kernel name block but rather the ascii distro block. (aka. put it somewhere after Radix or Raspbian, don't put it after BSD or Linux)

You can test the ascii with the command ./neofetch --ascii_distro redcatOS

It is based on Linux, it just shows tux

[hykilpikonna]

The command shows tux because the ASCII art is misplaced. It should show your ascii logo if it's written correctly. (For example, if you try ./neofetch --ascii_distro fedora it would show a fedora logo)

You can fix it by moving the ASCII art to the correct place after Radix or Raspbian.

This is literally for my custom operating system
