Add SW_Push_1P1T_NO_E-Switch_TL3301NxxxxxG

[diegoherranz]

Based on SW_Push_1P1T_NO_6x6mm_H9.5mm

Switch series: https://www.e-switch.com/product-catalog/tact/product-lines/tl3301-series-smt-tactile-switches#.XhzTa9_nhmA
Datasheet: https://sten-eswitch-13110800-production.s3.amazonaws.com/system/asset/product_line/data_sheet/158/TL3301.pdf

N actuator so that is is 4.3mm high. Can't be generic since I'd like this to have a 3D model and in fact it is very similar to SW_SPST_PTS645 which was added here (KiCad/kicad-packages3D#373) and the source was contributed too, so it should be relatively easy to add at some point.

Thanks!

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.

Be patient, we maintainers are volunteers with limited time and need to check your contribution against the datasheet. You can speed up the process by providing all the necessary information (see above). And you can speed up the process even more by providing a dimensioned drawing of your contribution. A tutorial on how to do that is found here: https://forum.kicad.info/t/how-to-check-footprint-correctness/9279 (This is optional!)
