Brainio val and local

[mike-ferguson]

Add Local Packaging and Upload Validator

New Features

Local Packaging Functions

• Added package_stimulus_set_locally() and package_data_assembly_locally() to save data locally instead of uploading to S3
• Functions save to ~/Downloads/brainscore_packages/ by default with custom path support
• Maintains same validation and file processing as original S3 functions
• Returns file paths and SHA1 hashes for data integrity

Upload Validator

• Created upload_validator.py with comprehensive validation for stimulus sets and assemblies
• Validates required columns (stimulus_id + at least one other), data types, and compatibility
• Integrated validation into local packaging functions with clear error handling
• Prevents packaging of invalid or incompatible data

Usage

# Instead of S3 upload
package_stimulus_set_locally(proto_stimulus_set, "identifier")
package_data_assembly_locally(proto_data_assembly, "identifier", "stimulus_id")

Benefits

• No S3 dependencies for local development/testing
• Same validation and processing as production functions
• Clear error messages for invalid data
• Working examples for plugin development
