Allow babelInlineConfig to be passed in

[Globegitter]

We are creating our babelConfig programatically and with babel-jest it is already possible to pass that in, but not here. With these changes I can now write my custom vue-jest transform in the following way:

...
module.exports = {
    process(src, filename, jestConfig) {
        return vueJest.process(src, filename, jestConfig, {}, babelOptions);
    },
};

Tests are passing now.

I think this should be added to the Jest config option object, rather than added as an extra object. Could you also please add some tests?

@eddyerburgh - done. Check #110 / #111 .

[justinhelmer]

I believe this PR can be closed now that #111 has been merged.

@justinhelmer thanks for that I will check it out but it does sound good.
