Doesn't work with the latest reactPHP promise v.3.2 #22

When installing with composer:

composer require clue/shell-react:^0.2

Get this response from composer:

Problem 1
- Root composer.json requires clue/shell-react ^0.2 -> satisfiable by clue/shell-react[v0.2.0].
- clue/shell-react v0.2.0 requires react/promise ~1.0|~2.0 -> found react/promise[v1.0.0, ..., v1.3.0, v2.0.0, ..., v2.11.0] but it conflicts with your root composer.json require (3.2.0).

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

I can see this is an older project but your docs page mentions v8 php, so I thought it might have been upgrade with the latest reactPHP.

I'd like to test out this reactPHP shell.. because I've been struggling to get a live interactive shell using the hello world examples for https://reactphp.org/child-process/ .. ie. that when I create a terminal for mysql, python, or other shell terminal, I've been looking to create a non-blocking client to that terminal, that I can use. But instead the IO is blocked because this kind of terminal doesn't provide a return signal back to the childprocess.

I was hoping your reactPHP shell might provide the solution for this situation.
