#pragma once and #ifdef/#define are redundant

[FunMiles]

Every include file starts with #pragma once and continues with #ifndef FILENAME_H and #define FILENAME_H The two methods do fundamentally the same thing. I would remove the #ifndef / #define / #endif as it is more verbose and supposedly, #pragma once can be more efficient. Supposedly, not all compilers have supported #pragma once, but GCC and Clang do and I have yet to encounter a modern compiler that does not. The pico SDK uses GCC, so even if some exotic compiler does not like #pragma once, it is not an issue for this project.

I left it in as it was auto generated by my IDE. I'll look into it in a couple of days

My IDE used to generate only the #ifndef version. I modified its template to only generate #pragma once. You might consider doing likewise.

Ok, so this was fixed a while back with no issues.
