Experimental esp-idf native cmake build (espressif#7)
* Implement native esp-idf cmake build Move `build.rs` contents to `build_pio.rs` Add feature `native` Add optional dependency `strum` * Remove main wrapper * Fix patches not getting applied, use correct patches * Clarify some `Chip` methods, fix python virtualenv path Use correct target name for `riscv32`. * Fix pio build, tidy code Fix potentially using `:` to split PATH on windows. * Add documentation to README * Change DEFAULT_SDK_DIR to `.espressif` Set min python version to 3.7. Set default build feature to pio. Make `native` feature usable. * Track `sdkconfig` and `sdkconfig_defaults` files.
