Repository: celestiaorg/celestia-app

Issue:
`make install` redownloads all embedded binaries each invocation
## Context

Currently on `main`, running `make install` multiple times will result in re downloading the v3 embedded binaries even if they haven't changed

## Proposal

Skip downloading the v3 embedded binaries if they're already up to date

Discussion:

 Not only does doing this allow for easy trust minimized message inclusion checks for specific messages by light clients, but also allows for the creation of message inclusion fraud proofs for all messages in the block. This is important to reduce the trust assumptions made by light clients.
