There is no possibility to set jsonNodeFactory when working with patches.

Issue copied from: java-json-tools#110

I would like to use the library withExactBigDecimals, i.e keeping 25.000 when patching a node.

@Test
void testDecimalsKeptAfterPatch() {

    ObjectMapper mapper = new ObjectMapper()
        .enable(DeserializationFeature.USE_BIG_DECIMAL_FOR_FLOATS)
        .setNodeFactory(JsonNodeFactory.withExactBigDecimals(true));

    JsonNode newer = mapper.readTree("25.000");
    JsonNode older = mapper.readTree("24.444");
    JsonNode apply = JsonMergePatch.fromJson(newer).apply(older);

    assertEquals("25.000", apply.asText());
}

org.junit.ComparisonFailure: expected:<25[.000]but was:<25[]>
Expected :25.000
Actual   :25

Is it possible to inject the behaviour I am after? The JacksonUtils that JsonMergePatch is using sets the factory to JsonNodeFactory.instance and I cannot see a way around this. I would prefer to use the JsonNodeFactory.decimalsAsIs for my specific case.

This also applies to the JsonDiff.asJson(older, newer) with the same behaviour as the above example.
