Release notes

• Many updates to refactor / clean / re-organise the repository (without actually changing functionality). #2190, #2191, #2192, #2197, #2201, #2204 This puts us in a good state for future API refactoring and development.
• When using packages with Pyodide, automatically cache repeatedly required packages so bootstrap speed improves. #2205
• Add a new JavaScript donkey API that makes it easy to spin up PyScript workers for future Python work without the need to use <script> tags to start PyScript. #2210
• Improved memory usage when multiple workers/interpreters are used on the same page. #2195
