Merge pull request #4579 from RosettaCommons/revert-4570-mlnance/sugar/fix_OMe_seq_on_read_in
Temporarily revert "Fixing pose building from saccharide sequence"
Reverts #4570
Pull request #4570 unfortunately caused a slowdown in pose read-in. Certain unit tests are now timing out (which may or may not be due to the pose read-in slowdown). Certain integration tests are also failing to run (e.g. test1_benchmark and dna_interface_design), which is likely one or more separate, unrelated problems. Since we don't know what all needs to be fixed, it's probably best to revert the whole pull request, fix the problems in a branch, then re-merge. This pull request therefore temporarily reverts pull request #4570 so that we can do that. @mlnance @JWLabonte @roccomoretti @everyday847
