Are the variant representations reported by rnsps the same as reported by NCBI?

As brought up in #92 this should be checked. Does what we report in ncbi_snp_query_api() match what is reported in https://www.ncbi.nlm.nih.gov/snp/?

@jooolia is this still relevant?

Yes I think it should still be checked. I do not see where we have systematically checked this. However the additional unit tests that you added do reassure me, but I think this should still be checked.
