Add support to search for Ordinals by text/namespace

[sabbyanandan]

From Ordiflow (https://ordiflow.com/)

One important feedback is, it would be great if you provide an API to search ordinals based on text/namespace (Eg: example.sats, 0.bitmap, example.x, example.unisat). Hiro API has the ability to fetch data based on inscription details but not based on the namespace. And hence I was forced to use unisat APIs for this scenario alone.

@sabbyanandan Thanks for adding this as a feature. I am the one form ordiflow. Request your team to add an API to search the ordinals data based on text/namespace. Eg: sabby.sats, 0.bitmap, sabby.x, sabby.unisat, sabby.btc. This should fetch the same result as like the inscription number or inscription ID APIs. This will be a very useful feature not only for me, but also for other API consumers.

So request your team to consider this feature, if possible.
