Tokens pallet (#243) * Use Monero-compatible additional TX keys This still sends a fingerprinting flare up if you send to a subaddress which needs to be fixed. Despite that, Monero no should no longer fail to scan TXs from monero-serai regarding additional keys. Previously it failed becuase we supplied one key as THE key, and n-1 as additional. Monero expects n for additional. This does correctly select when to use THE key versus when to use the additional key when sending. That removes the ability for recipients to fingerprint monero-serai by receiving to a standard address yet needing to use an additional key. * Add tokens_primitives Moves OutInstruction from in-instructions. Turns Destination into OutInstruction. * Correct in-instructions DispatchClass * Add initial tokens pallet * Don't allow pallet addresses to equal identity * Add support for InInstruction::transfer Requires a cargo update due to modifications made to serai-dex/substrate. Successfully mints a token to a SeraiAddress. * Bind InInstructions to an amount * Add a call filter to the runtime Prevents worrying about calls to the assets pallet/generally tightens things up. * Restore Destination It was meged into OutInstruction, yet it didn't make sense for OutInstruction to contain a SeraiAddress. Also deletes the excessively dated Scenarios doc. * Split PublicKey/SeraiAddress Lets us define a custom Display/ToString for SeraiAddress. Also resolves an oddity where PublicKey would be encoded as String, not [u8; 32]. * Test burning tokens/retrieving OutInstructions Modularizes processor_coinUpdates into a shared testing utility. * Misc lint * Don't use PolkadotExtrinsicParams
