[FEATURE] Bash version

[dramikei]

It would be nice to have a simple Bash version of this tool, which can run on low power hardware like a Router running OpenWRT, Since because of OpenWRT's storage limitations we can't really have python nor docker in it.

Handled it here incase someone comes across this issue : wolnut-wrt

Didn't create a fork of the repo as it would lead to almost all of the existing code and files to be deleted.

(ofc used Opus for it, but tested thoroughly on my own infra before releasing)
