remove chain-registry/osmosis from math module

[pyramation]

let's instead use the new chain-registry/utils that Wen wrote and pass in assets/chain info dynamically

import { asset_list, assets } from "@chain-registry/osmosis";

[pyramation]

• [ ] import chain-registry and @chain-registry/assets to math module as devDependencies
• [ ] when the functions of math module are updated to require an additional argument of assets, the test cases need to be updated accordingly
