feat(katana): add chunk size limit for starknet_getEvents method

[coderabbitai]

dojo/crates/katana/rpc/rpc/src/starknet/mod.rs

Lines 494 to 513 in 8a9dc0c

	fn events(
	&self,
	from_block: BlockIdOrTag,
	to_block: BlockIdOrTag,
	address: Option<ContractAddress>,
	keys: Option<Vec<Vec<Felt>>>,
	continuation_token: Option<String>,
	chunk_size: u64,
	) -> StarknetApiResult<EventsPage> {
	let provider = self.inner.backend.blockchain.provider();
	let from = if BlockIdOrTag::Tag(BlockTag::Pending) == from_block {
	EventBlockId::Pending
	} else {
	let num = provider.convert_block_id(from_block)?;
	EventBlockId::Num(num.ok_or(StarknetApiError::BlockNotFound)?)
	};
	let to = if BlockIdOrTag::Tag(BlockTag::Pending) == to_block {
	EventBlockId::Pending

we should limit the chunk size to avoid getting dos by giving an insanely large value. the limit should be configurable through the cli
