* Move pallet-asset-conversion * update licensing * initial integration * Integrate Currency & Assets types * integrate liquidity tokens * fmt * integrate dex pallet tests * fmt * compilation error fixes * integrate dex benchmarks * fmt * cargo clippy * replace all occurrences of "asset" with "coin" * add the actual add liq/swap logic to in-instructions * add client side & tests * fix deny * Lint and changes - Renames InInstruction::AddLiquidity to InInstruction::SwapAndAddLiquidity - Makes create_pool an internal function - Makes dex-pallet exclusively create pools against a native coin - Removes various fees - Adds new crates to GH workflow * Fix rebase artifacts * Correct other rebase artifact * Correct CI specification for liquidity-tokens * Correct primitives' test to the standardized pallet account scheme --------- Co-authored-by: Luke Parker <lukeparker5132@gmail.com>
