* Add SignalsConfig to chain_spec * Correct multiexp feature flagging for rand_core std * Remove bincode for borsh Replaces a non-canonical encoding with a canonical encoding which additionally should be faster. Also fixes an issue where we used bincode in transcripts where it cannot be trusted. This ended up fixing a myriad of other bugs observed, unfortunately. Accordingly, it either has to be merged or the bug fixes from it must be ported to a new PR. * Make serde optional, minimize usage * Make borsh an optional dependency of substrate/ crates * Remove unused dependencies * Use [u8; 64] where possible in the processor messages * Correct borsh feature flagging
