feat(event): add keypress listener to control carousel navigation

[ElijahKotyluk]

Added keypress event listener to control carousel navigation.

Description

Created a mixin file that would add a keypress listener, listening for 39(right-arrow) & 37(left-arrow) keys, after the instance is created and remove it before the instance is destroyed.

Motivation and Context

Feature Request: #248

How Has This Been Tested?

I imported the mixin file to the carousel component, ran yarn dev and tested the arrow keys to see if the carousel images would advance forward or backward.

Hey @ElijahKotyluk, super cool! Thanks for making the PR - I'll take a look at the code tomorrow when I'm in the office, but super glad to have the feature :octocat:

so... any updates on this?

[ElijahKotyluk]

I don’t think this project is maintained anymore unfortunately. But it wouldn’t be hard to implement it yourself.

@ElijahKotyluk thanks for prompt reply. Implemented own solution without issues.

No problem at all. Glad you were able to achieve key press listeners with ease.
