Remove duplicates in final list

[szinn]

This PR addresses #156 and removes duplicates based on the Path entries.

Performance time is linear wrt number of entries.

[szinn]

Also added a flag to list (--hide-duplicates / -d) to control the removal

Great PR, right to the point. This is how I would have reimplemented it, thanks!

[szinn]

Hang on before merging - I'd like to see if there's a way to make it default on in sesh.toml rather than having to litter -d all over the place.

[joshmedeski]

I don't recommend that @szinn

I'd like people to opt-into it for now, in the future we could add something to the config file to allow users to opt-into it always.

[joshmedeski]

But I'm happy with the feature as-is today. We can add the config option as a future optimization.

[szinn]

No way to do it since doesn't appear to allow options yet - merge away!

Let me know if there's other tweaks elsewhere!

Should this now be available? (I've installed via homebrew.) The flag doesn't appear to work and I don't see it mentioned in the notes for any of the releases since this was merged.

Edit 1: On closer inspection, it does work in the command line (sorry about not noticing that). The use case that doesn't appear to work is adding the flag to the sesh list --icons command shown in the tmux example in the README.

Is there a way to use this flag as part of the tmux keybinding? (Apologies if this is just user error.)

Edit 2: Apologies! This was totally user error. I'd added the flag to the second sesh list command but not the first. Adding it to the first led to the expected behavior.

@ooloth glad you got it working. I intentionally left it out of the README examples and you have to manually opt-in to it yourself.
