How do we choose the threshold for non-reasonable values? Maybe we can determine an upper bound from trusted information like the buffer size, rather than have to pick an arbitrary threshold. Eg. looking at the Rust implementation, they don't resize `mini_block_bit_widths` until reading them [here](https://github.com/apache/arrow-rs/blob/8205c5421f2f08c22c74be909beaf8afb2774011/parquet/src/encodings/decoding.rs#L608-L609) and then [throw an error](https://github.com/apache/arrow-rs/blob/8205c5421f2f08c22c74be909beaf8afb2774011/parquet/src/encodings/decoding.rs#L626-L628) if they fail to read the expected number of bit widths. -- This is an automated message from the Apache Git Service.
