Edawson/scdl schema (#1030)

### Description

This MR implements a strict schema-defined header for SCDL archives.
This header stores metadata about the archive and its composite arrays,
including a version, the array lengths and data types, and information
about the RowFeatureIndexes. This adds the features necessary to fix
#999 as well as implement simple bit-packing of the rowptr, colptr, and
data arrays. It also should make SCDL more secure, enable strict
compatibility checking, and open the door to more performance
improvements.

Note: I am still wiring up the header to the archive. I will make a note
here when the MR is ready.

### Type of changes
<!-- Mark the relevant option with an [x] -->

- [ ]  Bug fix (non-breaking change which fixes an issue)
- [X]  New feature (non-breaking change which adds functionality)
- [ ]  Refactor
- [ ]  Documentation update
- [ ]  Other (please describe):

### CI Pipeline Configuration
Configure CI behavior by applying the relevant labels:

-
[SKIP_CI](https://github.com/NVIDIA/bionemo-framework/blob/main/docs/docs/user-guide/contributing/contributing.md#skip_ci)
- Skip all continuous integration tests
-
[INCLUDE_NOTEBOOKS_TESTS](https://github.com/NVIDIA/bionemo-framework/blob/main/docs/docs/user-guide/contributing/contributing.md#include_notebooks_tests)
- Execute notebook validation tests in pytest
-
[INCLUDE_SLOW_TESTS](https://github.com/NVIDIA/bionemo-framework/blob/main/docs/docs/user-guide/contributing/contributing.md#include_slow_tests)
- Execute tests labelled as slow in pytest for extensive testing

> [!NOTE]
> By default, the notebooks validation tests are skipped unless
explicitly enabled.

#### Authorizing CI Runs

We use
[copy-pr-bot](https://docs.gha-runners.nvidia.com/apps/copy-pr-bot/#automation)
to manage authorization of CI
runs on NVIDIA's compute resources.

* If a pull request is opened by a trusted user and contains only
trusted changes, the pull request's code will
automatically be copied to a pull-request/ prefixed branch in the source
repository (e.g. pull-request/123)
* If a pull request is opened by an untrusted user or contains untrusted
changes, an NVIDIA org member must leave an
`/ok to test` comment on the pull request to trigger CI. This will need
to be done for each new commit.

### Usage

This change is opaque to the user - the headers are not human-readable
on disk. For a full description of the format and how to interact with
it, see the `schema` directory in SCDL's source directory.

### Pre-submit Checklist
<!--- Ensure all items are completed before submitting -->

 - [ ] I have tested these changes locally
 - [ ] I have updated the documentation accordingly
 - [ ] I have added/updated tests as needed
 - [ ] All existing tests pass successfully

 # Release Notes
 
+## BioNeMo Framework v2.7
+
+### Updates & Improvements
+
+- Adds a header to SCDL archives, providing improved provenance tracking and supporting future releases. Also adds tracking of the AnnData API coverage in SCDL tests.
+  This header stores metadata about the archive and its composite arrays, including a version, the array lengths and data types, and information about the RowFeatureIndexes. This adds the features necessary to fix https://github.com/NVIDIA/bionemo-framework/issues/999 as well as implement simple bit-packing of the rowptr, colptr, and data arrays.
