Add Amphenol G40H11xxxxx 1x1 Mini-SAS HD connector

Add Amphenol G40H11xxxxx 1x1 Mini-SAS HD connector. Once this connector is reviewed, I can add 1x2 and 1x4 variants as well.

Datasheet: https://cdn.amphenol-icc.com/media/wysiwyg/files/drawing/g40h1xxxxhr.pdf
Screenshot:

3D model (proprietary; I will add a README.md with the links once this is merged): https://cdn.amphenol-icc.com/media/wysiwyg/files/3d/sg40h11331hr.zip

3D model holes and pins perfectly match the footprint holes and pads, so I don't think a dimensioned drawing is not necessary here.

Rule violations:

• F7.2: the datasheet specifies the anchor point, and KLC says that in case of oddly shaped components, the anchor point must follow the datasheet, so that pick-and-place works as intended.
• F7.3: the datasheet explicitly specifies the pad shape to within ±0.1 mm, and furthermore, there is only one way to place the component anyways.
• F9.3: I am using manufacturer models as per M1.2, and they use a different orientation than what KiCAD expects.

All contributions to the kicad library must follow the KiCad library convention

Thanks for creating a pull request to contribute to the KiCad libraries! To speed up integration of your PR, please check the following items:

• Provide a URL to a datasheet for the footprint(s) you are contributing
• An example screenshot image is very helpful
• If there are matching symbol or 3D model pull requests, provide link(s) as appropriate
• Check the output of the Travis automated check scripts - fix any errors as required
• Give a reason behind any intentional library convention rule violation.

• F7.2: As this is a press fit connector, sticking to the datasheet seems reasonable
• F7.3: Please fix
• F9.3: Please fix
• add RefDes on Fab

• PTH and NPTH dimensions are correct
• Fab, Silk and CrtYd are incorrect

Note that Fab should represent the actual body outline, an Edge.Cuts line can be added additionally.

• F9.3: Please fix

I'll change it, but, can you explain the rationale for this?

[chschlue]

M1.2 does not invalidate F9.3. In fact, M1.2 is (in technical terminology) utter crap.
The goal of kicad-packages-3D is to collect as many free 3D models for kicad-footprints as possible and FPs should use a standardized 3D model reference so the 3D model can be added later without touching the footprint again.

BTW, this PR also has some wrong dimensions but I'm still working on that.

Fixed F7.3 and F9.3.

I believe there's already RefDes on Fab:

(fp_text user "%R" (at 0 -9) (layer F.Fab)

Will address wrong dimensions a bit later.

I believe there's already RefDes on Fab:

Ah, yes, it's hiding behind Silk. Please move inside the Fab outline.
