Ignoring styled-jsx

Hi,

I'm working on our UI Library and I want to convect all the components to string so we can shown it as code ready to copy and paste.

We use styled-jsx and we need to convert snippets like this ⬇️ into strings.

```
Save
{`
.address{
grid-template-columns: 66% 28%;
display: grid;
justify-content: space-between;
}
`}
```

This is the current output:

```

Name Last Name Address Country Do you own a car? Colors Save <_class styleId={2524236662} css='.address[data-jsx="2524236662"]{-ms-grid-columns: 66% 28%;grid-template-columns: 66% 28%;display: -ms-grid;display: grid;-webkit-box-pack: justify;-ms-flex-pack: justify;justify-content: space-between;} /*@ sourceURL=components/ui-library/Forms.js */ /*# sourceMappingURL=data:application/json;base64,eyJ2ZXJzaW9uIjozLCJzb3VyY2VzIjpbIi9Vc2Vycy9yaWNhcmRvcmF1Y2gvU2l0ZXMvc2NhbGVhcGkuY29tL2Zyb250ZW5kL2NvbXBvbmVudHMvdWktbGlicmFyeS9Gb3Jtcy5qcyIsImNvbXBvbmVudHMvdWktbGlicmFyeS9Gb3Jtcy5qcyJdLCJuYW1lcyI6W10sIm1hcHBpbmdzIjoiQUE0SGtCLGdDQUV1QiwwQkFDakIsQUFEaUIsK0JBQ2pCLGtCQUNpQixBQURqQixjQUNpQiwwQkFDaEMsQUFEZ0MsdUJBQ2hDLEFBR />

```
And I want to hide:

`/*@ sourceURL=components/ui-library/Forms.js */ /*# sourceMappingURL=data:application/json;base64,eyJ2ZXJzaW9uIjozLCJzb3VyY2VzIjpbIi9Vc2Vycy9yaWNhcmRvcmF1Y2gvU2l0ZXMvc2NhbGVhcGkuY29tL2Zyb250ZW5kL2NvbXBvbmVudHMvdWktbGlicmFyeS9Gb3Jtcy5qcyIsImNvbXBvbmVudHMvdWktbGlicmFyeS9Gb3Jtcy5qcyJdLCJuYW1lcyI6W10sIm1hcHBpbmdzIjoiQUE0SGtCLGdDQUV1QiwwQkFDakIsQUFEaUIsK0JBQ2pCLGtCQUNpQixBQURqQixjQUNpQiwwQkFDaEMsQUFEZ0MsdUJBQ2hDLEFBR`

My code:
```
let codeForm = jsxToString(
Form1,
{
shortBooleanSyntax: true,
ignoreTags: ['svg', 'img', 'div', 'style jsx']
}
);
```

Thanks for this amazing lib!

Start from the jsxToString call and its ignoreTags option shown in the issue, then trace how styled-jsx output is handled. Done means the generated string omits the styled-jsx element and its sourceURL/sourceMappingURL comments while preserving the other JSX output.
