Passage from 3.5.9 to 3.6.1 is not backwards-compatible (causes errors with Angular 5, rxjs < 6))

Hello,

This is too late to change, but a warning in the documentation could be useful: using ngx-select-ex above version 3.5.9 with our Angular 5 application breaks the application, with hard-to-interpret errors in the console. For example, using version 3.6.1:

ERROR TypeError: Object(...) is not a function

@RozennK I assume I can release 3.5.10 version with your notices. I think it should work
