Feature Request: Supports legacy lz4 decompression

[dantengsky]

It is really awkward to request this feature since lz4 is deprecated in parquet2, but unfortunately:

• We have some legacy data that have been written using the legacy lz4 compression algo, and backward compatibility is a must for us

• Although we have an internal patched branch of parquet2 as a workaround, a "vanilla version" of parquet2 is much much more preferred

Thus: Is it possible that parquet2 supports legacy lz4 decompression? (It is fully understandable that if this FR and the accompanied PR are rejected)

We should definitely support it - I just did not have the time yet to work on this :( Would you be able/willing to work on it?
