OR filtering to API endpoints

Is your feature request related to a problem? Please describe.

Currently you need multiple requests if you want to get the same data for (for example) a number of delegates:

https://explorer.ark.io:8443/api/v2/delegates/arkx
https://explorer.ark.io:8443/api/v2/delegates/itsanametoo
https://explorer.ark.io:8443/api/v2/delegates/thegoldenhorde

Describe the solution you’d like

An OR operation so I can fetch the data in a single request:

https://explorer.ark.io:8443/api/v2/delegates/arkx,itsanametoo,thegoldenhorde

Describe alternatives you’ve considered

Additional context

Best place for this would probably be the search endpoint, where it would match wallets and transactions. A POST to /api/v2/delegates/search:

{
  "usernames": [
    "arkx",
    "itsanametoo",
    "thegoldenhorde"
  ]
}
