Add a lot more data to info.json (#13366) * add some split data to info.json * add tags * add half of config_options.md to info.json * add support for designating master split * sort out split transport and primary * fix bad data in UNUSED_PINS * fixup custom transport * wip * allow for setting split right half keyboard matrix * add SPLIT_USB_DETECT * minor cleanup * fix an erroneous message * rework split.usb_detect * adding missing rgblight vars to info.json * add mouse_key to info.json * add all remaining options from docs/config_options.md * fix audio voices * qmk info: Change text output to use dotted notation * tweak layout output * resolve alias names * break out some functions to make flake8 happy * add a field for bootloader instructions * qmk generate-info-json: add a write-to-file argument Adds an argument that instructs qmk generate-info-json to write the output to a file instead of just to the terminal. * -arg_only, +action Because it was never my intention that one would have to specify a value for the argument that enables writing the file. * Bring qmk generate-info-json inline with other generate commands * pytest fixup * fix esca/getawayvan * fix data driven errors for bpiphany converters * features.force_nkro -> usb.force_nkro * split.primary->split.main * fix esca/getawayvan_f042 * fix the bpiphany converters for real * fix bpiphany/tiger_lily * Apply suggestions from code review Co-authored-by: Nick Brassel <nick@tzarc.org> * fix generate-api errors * fix matrix pin extraction for split boards * fix ploopyco/trackball_nano/rev1_001 Co-authored-by: James Young <18669334+noroadsleft@users.noreply.github.com> Co-authored-by: Nick Brassel <nick@tzarc.org>
