feat: add FPDecimals (#24)

* chore: make volatility query response optional

* chore: fix linting

* chore: remove schema and failed tests from CI until fixed

* feat: add math lib from nebula-contracts

* taken from https://github.com/nebula-protocol/nebula-contracts/tree/a5ff0e3e4285e38a310c7a6e024f6e3e2b75c538/libraries/cluster-math

* feat: use new FPDecimal

* fix: add cargo debug config

* fix: update injective math dependencies
