Constant bp_rococo::MAX_AUTHORITIES_COUNT

pub const MAX_AUTHORITIES_COUNT: u32 = 1_256; // 1_256u32

Maximal number of GRANDPA authorities at Polkadot-like chains.

Ideally, we would set it to the value of MaxAuthorities constant from bridged runtime configurations. But right now it is set to the 100_000, which makes PoV size for our bridge hub parachains huge. So let’s stick to the real-world value here.

Right now both Kusama and Polkadot aim to have around 1000 validators. Let’s be safe here and take a bit more here.
