Add filter for already built dependencies

[Rag0n]

Resolves #71

If version of pod is updated, then there will be an error during pod install, eg change version of SVProgressHUD inside development pod Core from ~> 2.0 to = 2.2.0:

[!] CocoaPods could not find compatible versions for pod "SVProgressHUD":
  In snapshot (Podfile.lock):
    SVProgressHUD (= 2.2.5, ~> 2.0)

  In Podfile:
    Core (from `..`) was resolved to 1.0.0, which depends on
      SVProgressHUD (= 2.2.0)

It seems like you've changed the constraints of dependency `SVProgressHUD` inside your development pod `Core`.
You should run `pod update SVProgressHUD` to apply changes you've made.

Sorry for my slow response. I'm do a large refractor these days. Can't merge it before I finish it.🤣

@leavez please let me know if you have any tasks that you feel comfortable delegating in your large refactor. My team is dying to get the ability to use this plugin for Pods that exist in multiple targets, so we're really looking forward to the next major release. I'm happy to help contributing if there's anything you need.

@leavez how are you doing - is there any update to the refactor (& this PR)?
