bobcat-precompiles

Calling features for https://github.com/fluidity-money/superposition-precompiles, Arbitrum, [https://code.markovgeist.org/precompiles](Markov Geist), and EThereum.

Note on tickmath-local: this feature will enable the local tickmath calculation instead of using the precompile contract. This is generally not desirable, and should only be used in the testing context. The reason is that it's not necessary to cast to and from our sdk primitive type (U) and the stylus-sdk preferred type, U256. Users making use of stylus-sdk should prefer the limbs form, or the version that converts directly to u160.
