IEquality Hotfix

[nbollis]

Last IEquality adjustment broke a few things in MetaMorpheus. This PR rectifies that and adds default interface implementations, pointing the derived classes at that default.

• Added IEquatable<IBioPolymer> and IEquatable<IBioPolymerWithSetMods> implementations in IBioPolymer.cs and IBioPolymerWithSetMods.cs.
• Updated Equals and GetHashCode methods in Protein.cs and PeptideWithSetModifications.cs to use the new interface.
• Added new test cases in TestOligoWithSetMods.cs to verify equality and inequality.
• Updated Equals and GetHashCode methods in OligoWithSetMods.cs and NucleicAcid.cs to use the new interface.
