Investigate adding finalized tag to block metadata

[emostov]

Proposed Change or Idea

If a user queries a block by ID it would be convenient for them to immediately know if it is considered finalized at the time of querying.

An alternate would be for the user to query blocks/head and compare that block's height to the block they are checking if it is finalized. If the height of the block they are checking finality for is higher then blocks/head they can assume it is not finalized

Seems like a good QoL improvement for users. I like it.

@dvdplm @emostov Would you guys like a simple key such as isFinalized: boolean to be returned in the output reponse?

[emostov]

@TarikGul yes, I personally like finalized: boolean.
