Description

libraries/WiFiProv/src/WiFiProv.h does not appear to have include guards, causing issues if it is included multiple times from a project split into multiple source files / headers.

Other libraries seem to correctly have the usual

#ifndef <something>_H
#define <something>_H

blocks as expected, so I imagine this is a simple oversight?

This results in predictable compilation errors:

In file included from <snip>\myCustomProvCode.h:3,
                 from <snip>\myProject.ino:13:
<snip>\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.2\libraries\WiFiProv\src/WiFiProv.h:24:5: error: 'WIFI_PROV_SCHEME_SOFTAP' conflicts with a previous declaration
     WIFI_PROV_SCHEME_SOFTAP,
     ^~~~~~~~~~~~~~~~~~~~~~~

Sketch

Something like this:

Sample.ino:


#include <WifiProv.h>

#include "myCustomProvCode.h"

myCustomProvCode.h:

#include <WifiProv.h>

will trigger the compilation error above.

### Debug Message

```plain
