Change version of RxSwift dependency in podspec

[maxxx777]

Hello,
We are migrating our project from Swift 4.1 to Swift 4.2.
The project and all its dependencies (except ReCaptcha) are using RxSwift 4.4.0. The problem is ReCaptcha 1.4 can not use version 4.4.0 of RxSwift because of rx.dependency 'RxSwift', '~> 4.3.1'
May it be replaced with e.g. rx.dependency 'RxSwift', '~> 4.3'? (ReCaptcha has no conflicts with RxSwift 4.4.0)

Please let me know if I could make PR to update podspec file.

Hi @maxxx777, thanks for the heads up. That seems like a simple enough fix. Do you want to try and tackle that with a PR?
