Using zlib with mermaid plugin in line with mermaid.ink using pako to compress

[leonards]

mermaid.ink uses compression to keep the data small. On the other hand, structurizr plugin example doesn't. It might be a good idea to implement this for potentially larger / more complex diagrams.

Based on the information found in mermaidjs/mermaid-live-editor#41 (comment), I created a rudimentary code on the structurizr example plugin MermaidEncoder.java:

    public String encode(String mermaidDefinition) {
        String s = String.format(TEMPLATE, mermaidDefinition.replaceAll("\n", "\\\\n").replaceAll("\"", "\\\\\""));

        byte[] compressedData = null;
        try {
            compressedData = compressData(s.getBytes(StandardCharsets.UTF_8));
        }
        catch(Exception e) {
            e.printStackTrace();
        }

        return "pako:" + Base64.getUrlEncoder().encodeToString(compressedData);
    }

    private byte[] compressData(byte[] input) throws Exception {
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        try (DeflaterOutputStream deflaterOutputStream = new DeflaterOutputStream(outputStream, new Deflater(9, false))) {
            deflaterOutputStream.write(input);
            deflaterOutputStream.finish();
        }
        return outputStream.toByteArray();
    }

The above is working in my environment. Can this enhancement be included into the plugin?
