New source: Codon Optimization

Description

Should return a codon-optimised sequence (whatever that means) from an entire sequence or a feature in the sequence. The tool that could be used is DnaChisel.

Checklist

• Add it to Source.jsx.
• Include a "finished source text" in FinishedSource.jsx.
• Include it in the right selection group in SourceTypeSelector.jsx (whether it takes no input, a single input or 1+ inputs).
• Include the endpoint in the backend API that the source uses in sourceFunctions.js > classNameToEndPointMap.
• You may have to add it to the right place in source_input_constrains.cy.js.
• If it has primers,
  • Prevent primers used in the source from being deleted in PrimerList.jsx > getUsedPrimerIds.
  • Implement the shiftSource and mergePrimersInSource functionality in cloning_utils.js.
• Make a test

Start by tracing existing source implementations in Source.jsx, FinishedSource.jsx, SourceTypeSelector.jsx, and sourceFunctions.js, including classNameToEndPointMap. Check source_input_constrains.cy.js and the primer-related files only if this source uses primers, then add the backend endpoint and a test; done means the source is selectable, produces a finished source text, and is covered by tests.
