My personal Fcitx5 input tables.

The CMake code was nabbed directly from https://github.com/fcitx/fcitx5-table-other.

- The sydmath table is based on [agda-input](https://github.com/agda/agda/blob/7bc882012789200911852f5e4045150be2604b42/src/data/emacs-mode/agda-input.el) and [fcitx5-table-other's LaTeX table](https://github.com/fcitx/fcitx5-table-other/blob/master/tables/other/latex.txt)
