Ciphers (#17)

* add AES.java additions + Galois.java

* desc

used ECB and ECBExceptionless instead of seperate interfaces. AESECB done

* Twofish ECB developments, moved some files

* twofishecb done

* Update Factories.java

factories.java topology rewrite 👍

* Update Factories.java

fix whitespace + forgot to add AriaGCM + SerpentGCM

* desc

RC6ECB.java placeholders,
LE32.java

* encblk+decblk funcs

* RC6 done

* desc

- move Camellia to seperate
- create CamelliaECB (it sucks, will fix it more after)

* good fixes!

* Rmv 16bfix (#14)

* progress

some progress was made. next commit will be working on Aria.java (its large so may take some time)

* "invalid config"

* Update Aria.java

potential working!

* bugfix

* Sha224 fix (#15)

* Update SHA224.java

potential fix

* Update pom.xml

tested - works now!
the entire fix was adding * 8L to the padding calculator thing xD

* SHA384 is working

LESGO!

* Create SHA512.java

* Sha512 impl (#16)

* desc
* Update SHA512.java

* Update SHA512.java

oookay a bit of opencode and a lot of time later its solved!
