Feat/add-browser-support

[Peetee06]

This PR adds browser support.

I tried to get a mock server running for an integration test. But as far as I understand when running tests with --platform chrome, the tests run in a sandbox that doesn't get access to the server.

As a workaround we check if the correct client is instantiated.

Builds on #33 and #34, so we should merge those first.

@Peetee06 I've merged the #34 and #33, as they looked good. Once this is gtg lmk, I'll test it as well and we can merge this.

Btw, awesome work on adding tests as well.

@Imgkl can you please rebase the pre-release branch onto master, so I can fix the remaining conflicts? As soon as I can do that, this PR will be ready for review and I'll ping you again :)
