Use Vector instead of Array

[Simn]

E.g. here: https://github.com/HaxeFoundation/crypto/blob/master/src/haxe/crypto/Aes.hx#L10

Vector is significantly faster on some targets.

I'm planing to do this. At the moment vector copy() method ( for JS target) use blit() not slice() which give worse performance ( related to HaxeFoundation/haxe#8040 (comment))

Done. Get performance boost mostly fot Java , C# and Python.
Here are some test values for Java:

     New  vs Old
     BlowFish - 0.92s vs 2.89s
     Ripemd160 - 0.80s vs 1.01s
     TwoFish - 0.12s vs 0.22s
     TripleDes - 1.88s vs 3.48s
     Sha512 - 0.16s vs 0.21s
     Sha384 - 0.13s vs 0.22s
     Sha256 - 0.11 vs 0.19s
     Sha224 - 0.13s vs 0.20s
