 - A file `./src/constants/sk_enc_constants_{n}_{qis_len}x{qis_bitsize}_{t}.rs` is generated including the generic constants for the circuit. Note that we separate them from the input because these should be known at compile time.

+On top of that, the console will print an estimatation of the number of advice cells needed to compile the circuit in halo2 considering a single advice column and a lookup table of size 2^8. Spoiler: around 90% of the constraints are generated by the range checks on the polynomial coefficients.
