TODO reduce overhead of profiling a function

this is especially noticeable for small functions

# small_profiler

Simple header-only inline C++ profiling. Outputs a json that can be used with chrome://tracing as a frontend.

Include the header then put `PROFILE()` at the begining of any function you wish to profile.

## Example

```cpp

#include "small_profiler.h"

int main(int, char**) {

    PROFILE();

}

```

You can also profile arbitrary scopes as long as you give them a custom name

```cpp

#include "small_profiler.h"

int main(int, char**) {

    PROFILE();

    

    {

        PROFILE("WHILE_LOOP");

        int i = 100000;

        while(i --> 0) {}

    }

}

```

To view the graph go to chrome://tracing click 'load' and select the generated json file.

To turn off profiling define the macro `NO_PROFILE` before including the header file.

To change the name/path of the output file define the 'PROFILE_OUTPUT_FILE' macro and set it to a string
