view_state should not be limited to 101 keys

[frol]

With the current implementation:

read-rpc/rpc-server/src/modules/queries/utils.rs

Lines 60 to 62 in c1e12b8

	let keys_count = data.keys().len() as u8;
	if keys_count > MAX_LIMIT {
	return data;

view_state method truncates the output to 101 keys. How heavy would it be to allow up to 10k keys and, ideally, implement pagination?

Resolved with #145.

I have just tested it with:
