LATIN1 Supported encoding

Would like debezium postgresql connetor to support latin1 encoding (iso 88591) or any other custom encoding.

As a workaround, at our company, we amended the following to support LATIN1 encoding

1. NonStreamingWal2JsonMessageDecoder.java

LINE 51:

– final byte[] source = buffer.array(); // old line
++ byte[] content = Arrays.copyOfRange(source, buffer.arrayOffset(), source.length);
++ content = new String(content, StandardCharsets.ISO_8859_1).getBytes(StandardCharsets.UTF_8);

2. StreamingWal2JsonMessageDecoder.java

LINE 114:

– final byte[] source = buffer.array(); // old line
++ byte[] content = Arrays.copyOfRange(source, buffer.arrayOffset(), source.length);
++ content = new String(content, StandardCharsets.ISO_8859_1).getBytes(StandardCharsets.UTF_8);
