feat(bridge): return java throwable to node process

[MarkusJx]

Added a new property to each error, called cause which will contain the throwable from the Java process (if present):

import type { JavaError } from 'java-bridge';

try {
    // Call a method that throws an error
    someInstance.someMethodSync();
} catch (e: unknown) {
    const throwable = (e as JavaError).cause;
    throwable.printStackTraceSync();
}

Added a config option called asyncJavaExceptionObjects to control whether the Java throwable should be returned from async contexts. This is required as enabling this option will cause the JavaScript stack trace to be lost. This option is disabled by default.

import { importClass } from 'java-bridge';

const SomeClass = importClass('path.to.SomeClass', {
    asyncJavaExceptionObjects: true,
});

try {
    await SomeClass.someMethod();
} catch (e: unknown) {
    const throwable = (e as JavaError).cause;
    throwable.printStackTraceSync();
}

closes #102
