feat: ByteArray should impl Hash trait

[tdelabro]

In #6817 I said it should impl IntoIterator, and in a following comment #6817 (comment) I suggested I could impl the hash too

IntoIterator was taken care of in #6938, but hash is still missing

Hi,

I'd like to try my hands on this one. Thanks

Hi @Hoossayn,

The maintainer of this repo tends to not really assign issues.
But someone already gave it at try there: #7042
And it seems like there are some roadblockers.
You should probably focus on something else for now

Oh thanks for the heads up @tdelabro
