This PR refactors the table virtualization real index main state that was creating performance problems. The problem was that we kept track of all the real rows even if we only print 200 at a time in the application. This caused a crash when some users with 10k+ rows on a table tried to iterate over this state 10.000 times or more. The trade-off is that now we keep all real indices in a Map, and each virtual row uses a selector to go to this Map. This way if we want to reset the full Map, we just have to overwrite the base state that contains the map, and the 200 selectors will recompute. This happens for example when we delete a row. This now has a limited and negligible performance impact.

Does the world need another CRM?
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
