--blocks_per_json_file flag not working as expected

[boomanaiden154]

Using the following CSV, test.csv:

85c044897c2460,98.000000
3b31,45.000000

With the following command line invocation, assuming ./json exists:

./bazel-bin/gematria/datasets/convert_bhive_to_llvm_exegesis_input --json_output_dir=./json --bhive_csv=./test.csv --blocks_per_json_file=1

We get the following in ./json:

0.json  1.json  2.json

Note that we should only get two files.

0.json:

[
  {
    "Hex": "85c044897c2460",
    "MemoryDefinitions": [
      {
        "Name": "MEM",
        "Size": 4096,
        "Value": 305419776
      }
    ],
    "MemoryMappings": [
      {
        "Address": 65536,
        "Value": "MEM"
      }
    ]
  }
]

1.json:

[
  {
    "Hex": "3b31",
    "MemoryDefinitions": [
      {
        "Name": "MEM",
        "Size": 4096,
        "Value": 305419776
      }
    ],
    "MemoryMappings": [
      {
        "Address": 65536,
        "Value": "MEM"
      }
    ]
  }
]

2.json:

[]

We see one of the blocks duplicated, the second block shows up twice, we get an extra file, and the extra file is empty. This needs to be fixed.

BB is not actually duplicated. I apparently just can't look at hex values.
