[feature request] np.packbits / np.unpackbits, general BitTensors (maybe can be just tensors with dtype torch.bits8 or have a new dtype torch.bits introduced) and bit packed tensors utilities for saving memory / accesses, support for BitTensors wherever BoolTensors are used

More 2-bit packing related to quantization: https://github.com/pytorch/pytorch/pull/43077

torch.sum and torch.count_nonzero for bool types should be equivalent. is it the case? Do they allocate any intermediate tensors and upcast? In the ideal case, the should also not upcast...

@vak maybe file a separate issue about this

[playground] Bug: viewport of image imported from Markdown is way larger than viewport of same inserted image. Imported image then can overflow the editor bounds - instead a horizontal scroller is needed or some other solution, but not image overflowing the editor viewport

> For whatever reason the default image maxWidth in the playground is 500px but the default image maxWidth when importing from markdown in the playground is 800px. Thank you! This...

ENH: Add `out=` argument to `numpy.astype` function (for unification as well)

I agree that that there are workaround (and thanks for bringing attention to `copyto`!), but many other regular functions already have `out=` argument, so having it supported also for often-allocating...

Bug: markdown triple-backticks blocks get JavaScript lang-specifier added automatically after a markdown import-export rountdtrip (even when the content has not relation to JavaScript)

The new setting `Preserve newlines in Markdown` in v0.25.0 playground ![Image](https://github.com/user-attachments/assets/26142e14-0259-40f4-aff6-245837b787d1) solves the extra-newline appearing (might be nice to have it enabled by default), but the `javascript` lang-specifier still appears...

Bug: in Playground typing in markdown source box, actually jumps and chars start appear outside this source box

Bug: collapsible container is not being exported faithfully to markdown/html
