Feature Request: Integrate Mempool.space

[michaelWuensch]

Is your feature request related to a problem? Please describe.
It would be cool if transactions can easily inspected using the well known Mempool.space block explorer.

Describe the solution you'd like
Adding support to add a mempool.space instance in the polar network.

Additional context
It is already possible to achieve this, but it would be more convenient if it was a part of polar itself.
It can be done using https://github.com/ngutech21/polar-mempool
