[NEW] sysutils/glow

There is not much to say about glow. It is a tool
that renders markdown on terminal,and makes sure
that it renders beautifully at the same time.

I use this tool to proofread my blogposts,which
are written in markdown in my terminal emulator
and I quite like what I see. I also use it to
read README's of various projects.

Glow can:-

# Read from file
glow README.md

# Read from stdin
echo "[Glow](https://github.com/charmbracelet/glow)" | glow -

# Fetch README from GitHub / GitLab
glow github.com/charmbracelet/glow

# Fetch markdown from HTTP
glow https://host.tld/file.md

It is a pretty simple tool, and it is good at what it does
