For example app make number of emoji columns dynamic based on screen width

[timmaffett]

This change makes the number of columns for the emoji picker dynamic based on screen width. When running the example on windows I was surpised to see this ridiculous result:

Here instead is a more expected behavior for an emoji picker (this is the example with this PR added):

For clarity I split out all of the emoji size related calculations to the top of the build method to better illustrate to the users what is going on.

For mobile versions the number of columns remains a reasonable number (for Pixel3 emulator it remains 7 as it was hard coded, for more modern phones the number of emoji columns increases as one would expect).

Thanks for the nice package!

@timmaffett Thanks for your improvements to the example ! Code-wise it looks good to me, but I would like to avoid too much complexity in the basic example. I would prefer to create an extra example e.g. main-dynamic-columns.dart in the example folder. What do you think ?

@Fintasys I have moved the dynamic column sizing to it's own file.

I was just trying to illustrate it was a 9 pixel margin on both sides of the emoji. The compiler does the math so it is identical to writing 18. Maybe I need to explain that in a comment or just put 18.. 😜
