Pin blinker to version <1.8 as fix for #329.

[mpibpc-mroose]

As PyleniumIO relies on selenium-wire (which is no longer alive/maintained) and this project again uses blinker one would like to pin this "stack" to a working version.

selenium-wirein it's final version uses a private method of blinker which has been removed in the 1.8 release. As selenium-wire cannot be changed the only way is to pin blinker.

You've raised really good points! It's probably best to remove selenium-wire as a dependency. If someone wants to add similar functionality, they are welcome to!

Yes I agree. Removing the selenium-wire dependency would be the cleanest solution.

I'm closing this as we've now removed selenium-wire completely. This will be out in v1.21
