Fix japicmp API compatibility check for parquet-compression refactoring

The japicmp plugin fails because:
1. commons-pool classes (BasePoolableObjectFactory, GenericObjectPool) are no longer
   transitively available after removing the Hadoop codec pool path
2. Public codec classes were moved from parquet-hadoop to parquet-compression
3. CodecFactory was refactored to extend DefaultCompressionCodecFactory
4. Deprecated constructors in ParquetRecordWriter and ColumnChunkPageWriteStore
   changed their BytesCompressor parameter type

Add ignoreMissingClassesByRegularExpression for org.apache.commons.pool and
exclude all moved/refactored classes from the compatibility check.
