Rename @perspective-dev/viewer-charts, add missing chart types

[texodus]

This PR introduces @perspective-dev/viewer-charts (ported from #3160, @perspective-dev/viewer-webgl), and deletes (but does not yet deprecate) @perspective-dev/viewer-d3fc. This is a breaking change, upgrading to v4.5.0 will require using @perspective-dev/charts (this package has a compatible superset of its predecessor's API, though it has a new name and internals).

In addition, the new @perspective-dev/viewer-charts packages has been upgraded to mostly feature parity with the package it replaces. This includes:

• Adds nine new chart types in addition to the original three: X/Y Scatter, X/Y Line, Y Bar, X Bar, Y Line, Y Scatter, Y Area, Treemap, Sunburst, Candlestick, OHLC, Heatmap.
• Significant refactor internally - drops streaming API in favor of the new with_typed_arrays. While streaming is better for interactive performance of one large dataset, it is worse for throttling streaming udpates. I've left the batching structure of WebGL rendering in, but the Viewer API which supported streaming has been removed entirely.
• Visual regression tests using the swiftShader backend for playwright. We have tried this approach before (with HighCharts) and it was miserable, but this seems to works so far out-of-the-box without any nonsense.

Not featured in the old @perspective-dev/viewer-d3fc, the new @perspective-dev/viewer-charts has some improvements:

• Per-column chart_type ∈ {Bar, Line, Scatter, Area} and optional stack override. Flattened into columns_config, now enabled for Y-type charts; defaults (Bar + no stack override). Feature Request: Mixed-type charts to display multiple series types on the same chart #2938 Mixing Chart Types #2390 Mixing chart types in single view #2331
• All charts types now support locked/unlocked zooming (even categorical axes) as well as auto-fit (though this is not fully enabled in the UI yet, only via plugin-config).
• All chart types are now super fast. So fast, the Render Warning thresholds have all been increased to 1,000,000 rows.
