feat: calculate the width of columns based on their content

[MatteoGauthier]

Noticed the host column in the ggh output was cropped, here is a quick fix by calculating the width of columns using rows content length.

It works in interactive and non-interactive mode

No performance loss :

hyperfine -r 20 -N -w 5 './ggh --config' 'ggh --config'
Benchmark 1: ./ggh --config
  Time (mean ± σ):       1.7 ms ±   0.1 ms    [User: 1.0 ms, System: 0.6 ms]
  Range (min … max):     1.6 ms …   1.9 ms    20 runs
 
Benchmark 2: ggh --config
  Time (mean ± σ):       1.9 ms ±   0.1 ms    [User: 0.9 ms, System: 0.5 ms]
  Range (min … max):     1.7 ms …   2.0 ms    20 runs
 
Summary
  ./ggh --config ran
    1.08 ± 0.08 times faster than ggh --config

Hey there.
Please see the initial changes done in this PR #13
And then let's see how we move from that as I was about to merge that one

Hey ! Would love to see this MR accepted !

Hey there,
pardon my delay,
I've done a quick check and this doesn't take into account the screen size, which means that some columns will not be displayed if the screen is small (e.g. terminal is resized)
