Reverts commit 7978162: Move runtime_init into SDK library.
Fixes #5.
The linker script in the Raspberry Pi Pico C SDK defines a symbol called runtime_init and calls that function automatically just before calling main(). This is convenient, but it also makes it less obvious what's required to initialize the RP2040 after boot. I decided to make this call an explicit step for transparency into the boot process. Clients must call runtimeInit() from their main() function before they access any peripheral.
