Get rid of the intl extension requirement

[alexander-schranz]

I use this library inside a symfony project where intl is not required because symfony give a polyfill for it.

Currently its not possible to use this library without intl installed (composer will error). I would recommend to use the symfony intl polyfill https://github.com/symfony/polyfill-intl-icu instead of require ext-intl.

"symfony/polyfill-intl-icu": "^1.0",

Here is detailed answer "why not". But, I'll work on removal of ext-intl.
