Added BlackArch

Added ASCII art for BlackArch as mentioned in #1311 
As BlackArch has two logos - one is a red Arch logo with a black medieval sword (as seen here https://www.blackarch.org/blackarch-guide-en.pdf) and the other a neon blue version with a japanese katana (seen here https://www.blackarch.org/) - I did go with a middle thing.
