Function lido::find_authority_program_address

pub fn find_authority_program_address(
    program_id: &Pubkey, 
    lido_address: &Pubkey, 
    authority: &[u8]
) -> (Pubkey, u8)

Finds the public key and bump seed for a given authority. Since this function can take some time to run, it’s preferred to use Pubkey::create_program_address(seeds, program_id) inside programs.
