guess the number (#1608)

* init new pallet. C&P

* initial round timing logic and tests

* new randomness trait and crate (from raffle PR) to use in pallets and runtime

* build works

* add cli and PublicGetter

* broken approach with own trait. trying to just extend traits now

* empty on_initialize and on_finalize builds now

* on_initialize executes on_timestamp_set which starts a new round and draws a random lucky number which can be queried by cli

* cant make BoundedVec work reasonably. will use vec

* refactored to Vec

* fix recursion loop

* add unit tests

* limit number of guess attempts

* flow works with cli

* add total issuance getter

* nested guess-the-number subcommand and other cosmetics

* fmt

* better error logging

* remove set-balance command which was deprecated long ago

* cargo fix

* fmt

* clippy

* taplo fmt

* fix enclave test

* bump lockfile

* review comments fixed

* re-inject set-balance TC but feature gate for test

* fix cargo test

* make CI scripts use shielding via vault instead of set-balance

* restore enum order for TC to make cargo test work again

* fmt

* shuffle TC enum

* fmt

* pin TC,TG,PG enum encoding for upgrade compatibility

* explicit enum pin type

* use Charlie instead of Alice for sidechain demo to avoid genesis funds change

* fix clippy

* tiny alignment

* fix demo script bug

* fix some more

* align CI tests and use non-prefunded Charlie too

* charge fees to guess
