Sha256 > Main (#1)

* Update SHA256Advanced.java

ByteFromHex function

* OH MY GOD

45 mins of coding. my brain hurts lol. its likely i will move sha256 to its own package inside of hash as Digest and several other classes will be included in it so instead of plopping them inside of misc i think ill use a standalone package. thanks for reading my rant

* several sha components

finally made sha256 standalone package, added classes:
HMAC
HKDF (placeholder for now)
Hex
Digest too but i did that last night

* desc

maybe it done

* Update README.md

* COMPLETION!

XACrypto\SHA256 is officially finished in its entirety. I might still make more modifications tho lol

* Update XACrypto.java

yippie! i made a dumb mistake

* bug fix

TWO. GOD. DAMN. CHARACTERS. completely messed up the end hash. i used 0 instead of i inside a for loop. i want to die :)

* remove tests + update README + good riddance garbage messagedigest sha256

yip
