* add `CoveredCall` strategy which is a `LogNormal` with `tau` reintroduced and parameterization tailored to covered call use case

* fix covered call swap logic

* add same test coverage as lognormal

* handle case where timestamp > maturity in swap

* fix compute price functions to use sigmaSqrtTau instead of just sigma

* add getInvariant function for testing

* capital efficiency test

* add option to compute init data for covered call given amountY

* use initGivenY for cap efficiency tests

* test with 0.5 sigma and fix init test


* fix broken coveredcall tests, rm init_log_state test (was redundant)

* rm unused sqrt implementation, increase the percentage we increase and decrease approximated bounds in simulated swap logic

* fix swap invocations to pass empty bytes as last argument
