v1.1.0 to permit PWM output to 2 channels of slice

### Releases v1.1.0

1. Permit PWM output for both channels of PWM slice. Check [Request for Clarification on PWM Slices and A/B sides #5](#5)
2. Use float `instead` of `double` for frequency and duty-cycle
3. Add example [PWM_MultiChannel](https://github.com/khoih-prog/RP2040_PWM/tree/main/examples/PWM_MultiChannel) to demonstrate how to use both channels of PWM slice.
