chore: bump (#95)

- pola-rs/polars#25567 fixed in
`polars==1.36.0`
- `unnest_all` no longer necessary
(pola-rs/polars#12353 (comment))

fix: dataset serde (#94)

- fix stream-less dataset (de-)serialization
- update `TensorSource.__getitem__` annotations

chore: bump (#93)

- bump deps (incl. torchcodec)
- pre-commit -> prek

fix: pin polars==1.34.0 (#92)

pola-rs/polars#25567

feat: unified DuckDBDataFrameQuery (#91)

feat(rerun logger): columns <-> indexes decoupling (#90)

rerun logger:
- decouple component columns from time columns via `indices` (a la
sparse tensors) allowing for timestep-wise sparse column logging (useful
for `rmind` prediction viz)
- some schema refactoring
- blueprint specification is back

feat: add TreeBroadcastMapper (#88)

- add TreeBroadcastMapper
- update yaak dataset template
- use interpolation for pipefunc mapspecs in yaml
- bump ty

feat: (mostly) TensorDict dataset state + torchdata dataloader (#87)

- update dataset state from a pair of `pl.DataFrame`s to a combo of
- `data: TensorDict` for most sample keys (see
[blog](https://ppwwyyxx.com/blog/2022/Demystify-RAM-Usage-in-Multiprocess-DataLoader/#Serialize-to-a-torch-Tensor))
    - `meta: pl.DataFrame` for non tensor friendly dtypes
    - `streams: dict` for storing metadata about training-time readers
    
- add dataset saving/loading
- add a `torchdata` node-based dataloader
(https://meta-pytorch.org/data/beta/migrate_to_nodes_from_utils.html)
for thread workers
- minor config updates
- tests refactoring

chore: bump (#86)

oomph (#84)

A smorgasbord of changes prompted by memory-related experiments:
- sample aggregation from inputs is now part of pipeline
- support `return_results=False` (see
[`pipefunc.map`](https://pipefunc.readthedocs.io/en/latest/reference/pipefunc.map/))
- replace `pipefunc.helpers.collect_kwargs` with
`makefun.wrap_signature` to make functions taking variadic kwargs
pipefunc-friendly and avoid an extra kwarg aggregation step
- replace duckdb UDFs with native spatial functions
- update rerun logger
- bump deps
