Final re-encryption for multi-party interactive bootstrap

Description

Lead party's final step in the multi-party interactive bootstrap. Takes the aggregated shares pair from int_mp_boot_add() plus the common random element and the original ciphertext, produces the refreshed ciphertext at a fresh modulus level.

Usage

int_mp_boot_encrypt(pk, shares_pair, a, ct)

Arguments

`pk`	The lead party's `PublicKey`.
`shares_pair`	A list of `Ciphertext` objects — the aggregated shares pair from `int_mp_boot_add()`.
`a`	The common random element `Ciphertext` used in the per-party `int_mp_boot_decrypt()` calls.
`ct`	The original `Ciphertext` being refreshed.
