> {{Avro::DataFileReader}} in {{lang/perl/lib/Avro/DataFileReader.pm}} reads
> the whole block into memory and decompresses (deflate/bzip2/zstandard) with
> no bound on the output. A {{block_max_size}} attribute exists with a TODO but
> is never enforced.
> Enforce a configurable maximum decompressed size and fail decoding with a
> clear error when a block would exceed it. Add a test with a high-ratio block.
