NB: For significant changes, please remake the testdata as follows (from the schema/ directory)

Remake test_tflite_tokenizer.litertlm :
bazel run -c opt //schema:litertlm_export_main -- \
 --tokenizer_file=$PWD/schema/testdata//gemma3_tokenizer.spiece  \
 --tflite_file=$PWD/schema/testdata/attention.tflite \
 --output_path=$PWD/schema/testdata/test_tokenizer_tflite.litertlm  \
 --section_metadata="tokenizer:vocab_size=10000,algorithm=bpe;tflite:quantized=true,model_size=1234567"

Remake test_tok_tfl_llm.litertlm
bazel run -c opt //schema:litertlm_export_main -- \
