WIP: clap3.0.0-rc.7

[conradludgate]

clap 3.0.0 is going into official release soon, with that comes the long awaited removal of structopt

Waiting on clap-rs/clap#2869

[conradludgate]

Output compared from clap3 to the current structopt impl. Last test shows aliases still working

[conradludgate]

Small regression using InferSubcommands is that you cannot specify how to resolve ambiguous cases.

Originally, we supported atuin history l to be atuin-history-list and atuin history la to be atuin-history-last. The InferSubcommands setting just makes the base case an error

[pksunkara]

For those kind of conflict, alias will have to do. So add l as alias to list.

@ellie it's wholesome that my first PR here #1 was using structopt instead of clap and very soon we'll be reverting that 😅
