[client-v2] Reduce number of allocations while compression/decompression data

[chernser]

Describe the bug

There is an issue with com.clickhouse.client.api.internal.ClickHouseLZ4OutputStream and com.clickhouse.client.api.internal.ClickHouseLZ4InputStream:

• new byte array created for each block final byte[] block = new byte[compressedSizeWithHeader];
• uncompressed buffer is not cleared between interactions and causes extra allocation
