Convert script `we` from fish to POSIX shell

Add two new scripts:
- stump-choose-city
- stump-weather
The former one sets the default city used for weather. The latter
generates the output used by StumpWM’s mode-line.

A quick and useful script I often use is a ~curl~ request to [[http://v2.wttr.in/][v2.wttr.in]] to get a
weather forecast in the terminal. By default, I want the request to be about the
city I live in, but it is also possible for the script to accept as its
arguments a search inquiry.

This script does two things. First, I get to choose a location which
weather will be displayed in StumpWM’s mode-line. The script stores
the selected location in the file ~$HOME/.cache/weather-city~, but only
if the input is not an empty string, otherwise nothing will change.
Secondly, if this change is applied, ~stump-weather~ (described below)
is called in order to update what StumpWM displays.
#+begin_src sh
CITY=$(rofi -p "City:" -dmenu | sed -r 's/ +/\+/g')
if [ -n "$CITY" ]; then
printf "%s" "$CITY" > "$HOME"/.cache/weather-city
stump-weather > /dev/null 2>&1

This stript is quite simple: it displays some weather information in
the format /Location: weather temperature (felt temperature)/. We use
the content of the file ~$HOME/.cache/weather-city~ to know which
location to use in our request to ~wttr.in~. If ~wttr.in~ is unreachable
after two second, the request aborts and the script displays an error
message instead.
#+begin_src sh
CITY=$(cat "$HOME/.cache/weather-city")
WEATHER=$(curl wttr.in/~"${CITY}"?format="${CITY}:+%C+%t+(%f)" --connect-timeout 1 2> /dev/null)
if [ -n "$WEATHER" ]; then

A quick and useful script I often use is a ~curl~ request to [[http://v2.wttr.in/][v2.wttr.in]]
to get a weather forecast in the terminal. If the user passes no
arguments to ~we~, the script will use the location designated in
~$HOME/.cache/weather-city~. Otherwise, it will use the options passed
by the user.
