not thread-safe Synchronous reading works fine, but moving the .read() call into a thread causes crashes. #3

from pathlib import Path
import asyncio
from maccor_utility.read import MaccorDataRawFile

cwd = Path(__file__).resolve()
path2file = cwd.parents[1] / "test_data" / "231004_test_data_raw.024"

# ✅ synchronous usage works
file = MaccorDataRawFile(path2file)
file.read()

# ❌ but fails when called in a thread
async def read_in_thread(file):
    return await asyncio.to_thread(file.read)

file = asyncio.run(read_in_thread(file))
print(file)
