Generalized Poseidon Constant Generation

Lines 30 to 38 in ef2dd89

	/// Poseidon Prime Field Modulus Bit Count
	///
	/// This constant is denoted `n` in the Poseidon paper where `n = ceil(log2(p))`.
	pub const MODULUS_BITS: usize = 255;
	/// Security Level in Bits
	///
	/// This constant is denoted `M` in the Poseidon paper.
	pub const SECURITY_LEVEL: usize = 128;

@SupremoUGH: Can these two be general?

@GhostOfGauss: I agree, it would make more sense for them to be general. Though in light of this note it seems that maybe there's a restriction on which curves this algorithm applies to

	/// # Safety
	///
	/// The constants that are specified to be "secure" in this `struct` have only been guaranteed to
	/// work for BLS12-381.
