v0.2.1

What's Changed

• Fix incorrect parsing of spin operators in SpinCircuitSolver._embed_operator:
  The previous implementation of this method was not able to handle gates where the generator included terms that had a different number of non-identity operators. The new implementation of this method is able to handle the more general case as well.
• The API for a Cold Atom Job now takes a token instead of a password. Furthermore, get requests are no-longer done with an entry under json in the request params but are instead done using a job_id entry. Post requests are now done with the structure json={"job": ..., ...} instead of data={"json": ..., ...}.
