Re-make upper TKR frame brackets `GAPS-TKR-MEC-644` in AL-7075-T6 #135

The current brackets are made in AL-6061-T6 but do not have enough thread engagement to support a full torque (42-47 in-lbs) of a Grade 8 equivalent 8-32 bolt. When using Al-6061-T6 we'd need about 0.48" of thread engagement and we currently have a little less than 0.3". By re-making the brackets out of Al 7075-T6 the required thread engagement can be reduced to about 0.28".

The original 6061-T6 brackets have been install, but with only a torque spec of 25-30 in-lbs. I felt the threads were going to strip if I increased the torque any further. Since we don't have spares, I did not want to risk stripping the brackets.
