Can sharp expose remaining parameters of vips_sharpen()

[Rochel23]

I am trying to do unsharpmasking using sharp library. I am using sharpen operation to do so and I require the parameter flat/jaggy threshold(x1) to achieve the expected output .
As far as I understand, the parameters x1, y2 and y3 are not-yet-exposed. #708
Are these parameters planned to be exposed in near future? Can this be included in the new feature request? Or is there a way to achieve threshold(x1) for sharpen operation?

Happy to accept a PR that exposes these, if you're able.

I tried to look into the code, but I am no expert in cpp. Though it would be great to have this feature.

These are now available as of v0.30.3
