### Describe the bug, including details regarding any error messages,
version, and platform.
I had mistakenly put a duplicate field in my schema when calling
`pyarrow.json.read_json` with `ParseOptions.explicit_schema`
I was either getting seg faults or an error message that wasn't clear.
Given the nature of json, there shouldn't be duplicate fields in the schema.
`pyarrow.json.ParseOptions` should throw if there's any duplicate field in the
`explicit_schema`.
I can send an MR, I'm just wondering if there's anywhere else where we do
similar checks?
```python
import io
import pyarrow as pa
import pyarrow.json
SCHEMA = pa.schema(
[
pa.field("foo", pa.bool_()),
pa.field("foo", pa.bool_()),
]
)
with io.BytesIO(b'{"foo": true,"other": "bar"}') as buffer:
buffer.seek(0)
pyarrow.json.read_json(
buffer,
parse_options=pyarrow.json.ParseOptions(explicit_schema=SCHEMA),
)
```
```
pyarrow.json.read_json(
