Does this pakcage need an interface?

[jakobnissen]

Suppose someone who studied modified RNAs want to work with this package. So they create a new BioSymbol type (and an Alphabet type for BioSequences work).

Does it make sense to have an interface with what is minimally expected to implement? I suppose one can get away with implementing very little.

[TransGirlCodes]

Perhaps we define a BioSymbols interface as a set of unsigned values, that have all the basic operations, plus a trait defining whether the values are one-hot encoded, to conform with an interface around compatibility etc.

To facilitate fast IO, we probably also want to have some sort of ASCII shortcuts, i.e. being able to construct UInt8 from your BioSymbol effectively when they can be represented as such.
