Support for MacOS (Apple Silicon, M1) architecture (j2v8_macosx_armv7l).

Hi,

In our JVM-based project, we are using the J2V8 library. Here are the Maven dependencies we are using:

```

com.eclipsesource.j2v8
j2v8_linux_x86_64
4.6.0


com.eclipsesource.j2v8
j2v8_win32_x86_64
4.6.0


com.eclipsesource.j2v8
j2v8_macosx_x86_64
4.6.0

```

But since Apple build its new MacBooks on the M1 chips, we faced the problem in developing the application.

```
Caused by: java.lang.IllegalStateException: J2V8 native library not loaded
Caused by: java.lang.UnsatisfiedLinkError:
Could not load J2V8 library. Reasons:
no j2v8_macosx_armv7l in java.library.path
```

Are there any plans to provide builds for this architecture, or is it possible to build the library on such a machine? We can do build for our own, but we need help with how to do this.

Thanks.
