Hello! First of all I would like to really thank you for the work that you've put into this package. It's amazing what you were able to squeeze from mozart codebase.

I am replacing very old version of mozart to strauss on one of my projects and I've encountered slight issue with dependency to the elazar/flystream package. Strauss requires ^0.5.0 version which depends on psr/log:^1 version. My dependencies (monolog/monolog and symfony/console which are rather popular) requires psr/log (^2.0 || ^3.0) and psr/log (>=3) respectively.

Is it possible to bump required version of elazar/flystream to at least 1.0? As you can see the dependency to the psr/log was updated in 1.0 version.
