implemented layout limit

[webstack9]

Fixes #3
Fixes #200
Hi @Nyratas , I was trying to follow instruction from issue 200, this patch should be able to provide flexible layout with limit.

Yet #200 isn't a issue, it's a working pull request, you just changed how it behaved but the result is the same.

HI @Petoches , @Nyratas , may bad. Knowing how old is issue 3, I was thinking that pull request 200 was abended, my mistake I was seeing conflict message , and did not check conversation time.
Layout limits is very important for my project where I am using flexible, and reading yours conversation i wanted to try to help as well supporting this great package.
Yesterday whole day I was trying to make digitaloptimist/nova-translatable field validation work when inside flexible , and while I had this code opened and not have any progress with nova-translatable , I wanted to make my day better reverting my focus and layout limits.

As I see now that this is duplicate PR I will cancel this pull request.
