Readline dependency removed

[stellarpower]

Hi, nice shard.

It looks like Readline has been removed from recent versions of Crystal, would it be possible to remove the dependency?

Cheers

iirc there is only one place where Readline is used.

easy-cli/src/command_helpers/command_helpers.cr

Line 12 in 70a1b32

input = Readline.readline(pr)

If you want to submit a PR for that go for it. Otherwise I'll find some time soon
