Exclude unused dependencies from `crypto-conditions`

[sappenin]

This library only uses the PreimageSha256 crypto-condition type, so this kind of warning is a false positive. We should try excluding unused crypto-conditions dependencies from the build to see if these warning go away.

Hello! I've read the description, and this seems to be a dependency exclusion task to prevent some warnings. I'd like to give it a try. Please assign this to me.

Hi @juliateles99, sounds great, thanks for getting involved!

As part of this work, be sure to exclude net.i2p.crypto dependencies from the jackson-datatype-cryptoconditions dependency too. Read more in this comment.
