T1[1] gen
apply shiftRows from lastXor in cascade to T2 input in firts round
new macros for 128-bit XOR, preparations for XOR cascade
first draft of implemented external encodings - should work
XOR cascade fixed, external encodign fixed
XOR cascades fixed, external encoding fixed
works if IO is identity
added asserts to allocate & connect macros - to avoid problems when using them
stronger asserts with IOenc, works without IO, rules Tboxes indexed by col
application of col index rule for T1[0] box
works
external encodings - fixed bijections
application of external encodings - wrapping works
BGE attack - Rbox function with T1 tables. Not attacking r9
