TFHE new arrays in progress

[dwariyar]

Changes made so far:

• Updated older arrays into CpuFheUint8Arrays
• Using array masking instead of loop because indexing doesn’t work with this new array type. Ones and zeros are new encrypted arrays that work in combination with if_then_else and is_match to generate an increment mask.
• Changed array mask to be fully encrypted (may need to test if this particular if_then_else method works)

Issues:

• The .eq (Partial Eq) operator doesn't seem to work between an array and scalar as intended, so another method may be needed
