applet.interface.jtag_pinout: simplify TDI detection code. NFCI. Before this commit, _detect_tdi tries to discover every correlation between bitstream shifted into TDI and bitstream shifted out of TDO, returning multiple results as "multiple IR lengths". Not only this can't happen in any reasonable setup, but downstream code also cannot deal with it correctly either. After this commit, the first (and generally, only) correlation is returned, with an additional check for minimum IR length.

applet.interface.jtag_pinout: convert to nMigen.

README.md: update acknowledgement section

applet.program.mec16xx: clarify note on cursed behavior.

hardware: Add 3D printed case lid

hardware: Rename laser cut case directory

applet.internal.selftest: indicate pins-* as broken on >=C0. pins-pull is broken, too.

applet.internal.selftest: indicate pins-{int,ext} as broken on >=C0.

hardware: Add 3d printed case
