Suppress compiler warnings
This commit adds the allow(unused) attribute to functions and constants that are not currently used. There is one warning remaining but https://github.com/embassy-rs/cyw43/pull/23 attempts to address that one. The constants have been moved into a module to allow the attribute to be applied to the module as a whole. The motivation for this is that it will hopefully make it easier to spot new warnings that might be introduced by new, or updated code.
