Description
When swapping out moment.js with either day.js or date-fns, the generatePicker function imports all of the locales.
This results in a huge bundle and totally not needed in a lot of use cases.
dateFns.ts#L26
Is there a way to get around this?
It seems a little silly to have pre-loaded all locales when you only need one :)

Research direction
Start with src/generate/dateFns.ts at the linked locale import and trace how generatePicker selects date-library locales. Compare the resulting bundle impact for a single-locale use case; done means locales are not all included when they are not needed, with the existing picker behavior preserved.
