This function is used to obtain a SIRIUS refresh token with your login details, which allows
generateCompoundsSIRIUS to automatically log in to use e.g. CSI:FingerID.
getSIRIUSToken(user)A character string with the user name/email.
A character string with the (secret) refresh token or NULL if the input was cancelled.
SIRIUS version 5 requires the user to be logged in when using web services such as
CSI:FingerID. To allow secure log in by external software tools such as patRoon, a referesh
token is needed. This function uses your user name (email) and asks for a password (using getPass) to
obtain such a token more easily.
More details for e.g. account creation can be found on https://boecker-lab.github.io/docs.sirius.github.io/account-and-license/.
