Change go.mod module name, so that it can be imported from other projects

[alrevuelta]

Just wondering if it would be possible to change the go.mod module name from eth2-exporter to github.com/gobitfly/eth2-beaconchain-explorer or any other name with the GitHub prefix. This will allow other go projects to easily import your packages and use them. To the best of my knowledge, this is a common practice in golang repos.

Thank you for your interest in our project.
Created an internal ticket, will update here if we have new information. (currently a lot of work, will take a while)
