Check compressed state diff size before sending seq_commtiments

[ercecan]

          Is this only applicable to prover? because we also calculate the state diff size in the sequencer?

citrea/crates/sequencer/src/sequencer.rs

Lines 550 to 553 in 7a077f0

	// Serialize the state diff to check size later.
	let serialized_state_diff = borsh::to_vec(&merged_state_diff)?;
	let state_diff_threshold_reached =
	serialized_state_diff.len() as u64 > MAX_STATEDIFF_SIZE_COMMITMENT_THRESHOLD;
