[Enhancement] generic cross platform script to install glow on demand

[lgersman]

Hi everyone,

I need to install glow on demand on different platforms.

Some other software solutions provide a script (which can be curl'ed) installing the software in a cross platform manner :

# example : install fzf cross platform
wget -qO- https://raw.githubusercontent.com/junegunn/fzf/master/install | $SHELL -s -- --bin

It would be nice if you guys would provide such a script for glow.

Or - at least - provide a generic tar.gz for every platform. The one for linux amd is right now missing for example (only apk, deb and rpm are available).

Cheers,

Lars
