IEquality hot fix hot fix

[nbollis]

Refactor Equals methods and add IEquatable regions.

Removed Equals from IBioPolymerWithSetMods interface in Omics. This ensures it is called on one class and not the interface ambiguously so that any call in MetaMorhpeus uses the correct equals without needing understanding of the codebase to perform the operation correctly.

• Updated Equals in PeptideWithSetModifications to check OneBasedStartResidue and Parent?.Accession.
• Updated Equals in OligoWithSetMods to check FullSequence and DigestionParams?.DigestionAgent.
• Added IEquatable regions to PeptideWithSetModifications and OligoWithSetMods.
• Organized Equals methods with #region IEquatable directives.
