Relax logger dependency

[Drowze]

About the changes

Relax logger gem dependency, so unleash can be used with logger >= 1.6.5.

This should allow using unleash gem with logger 1.7.0 (which was released in 26/March).

Tests seem to pass locally.

I doubt that logger breaks it's API in a minor version change. Nothing particular jumps at me from looking at https://github.com/ruby/logger/releases/tag/v1.7.0 .

If all tests pass as expected, then there is no reason to not relax the dependency version.
