ws0ta trap case

Protection case for the ws0ta QRP traps available here: https://oshpark.com/shared_projects/nrjciEFR

The PCB was developed by [KE6MT](https://www.ke6mt.us/2018/12/ultra-lyte-summits-on-the-air-by-fred-kt5x/)
based on a design by WS0TA (aka KT5x) described [here](http://ws0ta.blogspot.com/2017/04/so-you-want-to-build-efhw-with-qrp-traps.html)

This case helps protect the toroid, and hopefully, does not change the Q of the coil (to be tested).
