chore: add annbatch

[ilan-gold]

Checklist for adding packages

Mandatory

Name of the tool: annbatch

Short description: A data loader and io utilities for mini-batched data loading of on-disk AnnData files as well as in-memory data, co-developed by Lamin Labs and scverse.

How does the package use scverse data structures (please describe in a few sentences): annbatch is built directly on anndata files, both in its preshuffler and loader. These files could come from other formats like spatialdata or mudata (as tables or mods), and we plan to add, at the minimum, mudata support.

• The code is publicly available under an OSI-approved license
• The package provides versioned releases
• The package can be installed from a standard registry (e.g. PyPI, conda-forge, bioconda)
• Automated tests cover essential functions of the package and a reasonable range of inputs and conditions [^1]
• Continuous integration (CI) automatically executes these tests on each push or pull request [^2]
• The package provides API documentation via a website or README[^3]
• The package uses scverse datastructures where appropriate (i.e. AnnData, MuData or SpatialData and their modality-specific extensions)
• I am an author or maintainer of the tool and agree on listing the package on the scverse website
• I agree to abide by the scverse code of conduct on all scverse communication channels

Recommended

• Please announce this package on scverse communication channels (zulip, discourse, twitter)

• Please tag the author(s) these announcements. Handles (e.g. @scverse_team) to include are:

  • Zulip: N/A, already done
  • Discourse:
  • Mastodon:
  • Bluesky:
  • Twitter:

• The package provides tutorials (or "vignettes") that help getting users started quickly

• The package uses the scverse cookiecutter template.

• I would like to be invited to the scverse Github organization

Go annbatch go!

Please fix the CI by using supported terms (or add missing terms - but remember that you'd then be the only package with this term and we're using them for our website) and then feel free to merge.
