Accessing library functions via function pointer seems to cause a reset.
Still investigating the cause.
- compile keymaps subdir as part of main src cmakefile, rather than as a
separate library.
- rather than setup table of function pointers and using an indirection
in the main code, set up a jump table (switch). This is cleaner.
- keymap files (c,h) are in src/Keymaps
- keymap files are added to the keymap library in src/Keymaps/CMakeLists.txt
- keymaps for the build are listed, along with positions, in /keymap_lists.cmake
- cmake generates a keymap jump table from the keymap lib and list
- tests mostly passing. Keymap structure for testing will be used as the model
for the app keymaps.
