Dayjs cannot parse from gggg

[Vbubblery]

I want to parse a date: 2019W19 with dayjs:

dayjs("2019W19","gggg[W]ww")

It dose not support yet,
But moment supports it already.

moment("2019W19","gggg[W]ww")

I had a use case for 2016-46 and solved it using

dayjs.utc("2016", "YYYY").startOf('isoWeek').add(46, 'weeks').toISOString()

---

EDIT

This approach fails for 2020-30. Here's my benchmark test suite and for the moment, momentjs still wins...

Any workarounds for now? Any plans to fix that?)
