[FEAT] use `wego` instead of `wttr.in` when installed

### Description

wttr.in is a frontend host to [wego](https://github.com/schachmat/wego)

if wego is installed (and maybe configured correctly, how to check?) should just use/parse that output instead. it does ssuccessfully output json, although I'm not sure if it's the same format as wttr.in

### Motivation

there's a delay when using fastfetch with the `weather` module because it's dependent on my network's latency. wego supports amount of caching. among other configurable things that `wttr.in` probably provides too but I'de like to self-host / cut out that middleman.
