Crystal 0.32.0 breaks icr

[lebogan]

Error message when I run make:

1 | require "readline"
Error: can't find file 'readline'

I had to add crystal-readline as a dependency to get it to work. This is a breaking change for version 0.32.0.

From CHANGELOG:

(breaking-change) Remove Readline from std-lib. It's now available as a shard at crystal-lang/crystal-readline (#8364, thanks @ftarulla)

Thank you for your attention.

PS - I love this utility!

Readline was removed, so we will need to include the shard separately.

This is fixed by #115.
