Motivations for removing the upper bound on Qiskit:
We've had several people be unable to use this library effectively while waiting on updates, and several PRs to update the version which have taken a while for us to release.
We do not have an automated way to bump & test new versions yet, so further delays happen between every new Qiskit version.
There doesn't appear to be an easy way to check what the breaking changes were in the Qiskit changelog anyway, so manual validation of new versions has limited value.
Closes #25
