I found arrow-cpp we can read the file because we don't check the decompress
size:
```c++
// Decompress the values
PARQUET_ASSIGN_OR_THROW(auto decompress_len, decompressor_->Decompress(
compressed_len - levels_byte_len, page_buffer->data() +
levels_byte_len,
uncompressed_len - levels_byte_len,
decompression_buffer_->mutable_data() + levels_byte_len));
if (decompress_len != uncompressed_len - levels_byte_len) {
throw ParquetException("Expected " + std::to_string(uncompressed_len -
levels_byte_len) +
" bytes but decompressed " +
std::to_string(decompress_len));
}
```
@wgtmac @pitrou Do you think we need to add the check above?
