custom metric for Fugue supporting

[lukeduongdnanexus]

I am using Whylogs to custom metric, and it work fine in whylogs.
but when I used fugue_profile, it return the error:
whylogs.core.errors.UnsupportedError: Unsupported metric: dx_base_metric
I traced and found that _METRIC_DESERIALIZER_REGISTRY do not have the new custom metric.
